Analysis of Prestressed Concrete Girder for Bridgesijtsrd
Today bridge building has gained worldwide importance. Bridges are the key elements in every road network and the use of pre stressed girder bridges is becoming more and more popular in bridge construction due to their better stability, service friendliness, economy and durability, aesthetic and structural appearance. Typically reinforced concrete construction, steel construction or steel composite construction is used. In the case of high spans, reinforced concrete construction is uneconomical due to the larger span. , the cross section is used more efficiently than the reinforced concrete cross section. Pre stressed concrete is used for long span bridges with a span of more than 10 m. Conventionally, when calculating bridges, the superstructure and substructure are analyzed separately. The superstructure is usually a grid made up of main girders, transverse membranes and a deck slab. a grid of linear elements The columns of the main girders are anchored. The superstructure is examined according to IRC 62014 and according to IRC 182000 for unconsidered gravitational loads and moving vehicle loads. Reduction of the stress level and also of the deflection compared to the straight tendon profile. Avinash Kumar Vidyarthi | Dr. P. K.

Ellis Island was where immigrants first arrived in America and were processed. They came with all their belongings and families. Housing for immigrants was typically cramped tenement housing or shanty towns built from scraps. Work was difficult to find and dangerous, but provided much needed money, so many immigrants including children as young as 6 years old took any job available even for low wages. The documents show the hardships immigrants faced as they established new lives in America.
Isambard Kingdom Brunel was an influential British engineer in the 19th century best known for designing numerous important bridges and railways. One of his earliest bridges was the 1838-39 Paddington Canal Bridge, which was recently discovered to be the first cast iron bridge designed by Brunel. The bridge was carefully dismantled and preserved during the Paddington LTVA bridge project, which replaced an existing bridge over 15 rail tracks and a canal near Paddington station in London. The project involved raising the existing bowstring arch bridge, constructing new support structures, and launching a new rail bridge deck between 2004-2006 while minimizing disruption.

How the London UNDERGROUND shaped LondonJIM MUKERJEE
The "London Underground" is celebrating its 150th anniversary in 2013. This presentation describes the initial trials and tribulations, dogged tenacity, and miraculous triumphs that transformed transportation, and people's lives, in Victorian London. Even today, the "UNDERGROUND" roundel logo, the "Tube Map", and imaginative posters, are instantly recognized worldwide as iconic symbols of one of the greatest cities of the world, steeped in history, culture, and commerce!
The document summarizes the history and development of rail transport from ancient times to the modern era. It describes some of the earliest trackways dating back thousands of years, as well as early wooden wagonways and tramways that transported materials. The key developments included the introduction of iron rails and wheels, which provided better durability. Steam power was introduced in the early 1800s, allowing for more powerful locomotives. Railways expanded rapidly in the 1800s with the development of stronger iron and steel rails. Electric power was introduced in the late 1800s, becoming the dominant power source for rail transport over the 20th century.
The transport network in 18th century Britain faced major problems. Roads were poorly maintained mud tracks, and travel between parts of the country took weeks. This negatively impacted industry, trade, and food supply. In response, Britain saw a transport revolution from 1750-1900 through improvements to roads, canals, and the rise of railways. Each new method sped up travel and movement of goods, fueling industrial growth. The complex new network brought both economic benefits and social changes to Britain.
The history of rail transport began in Ancient Greece in the 6th century BC. Over time, various systems using wooden rails, horse-drawn carts, and iron rails developed. In the early 19th century, the development of steam power and new rail technologies accelerated. Key events included Trevithick's steam locomotive in 1804, the Stockton and Darlington Railway opening in 1825 using steam locomotives, and the Liverpool and Manchester Railway opening in 1830 as the first intercity passenger railway. The development of rail transport was an important part of the Industrial Revolution. Pioneers like George Stephenson and his son Robert advanced steam locomotive and railway technologies.
Early attempts at steam locomotives in the late 1700s and early 1800s struggled with breakdowns and weak power. Richard Trevithick built the first steam locomotive to run on rails in 1804, pulling 10 tons of iron but breaking down after 100 yards. John Blenkinsop's 1811 design added extra wheels with cogs for better grip. "Puffing Billy" built in 1813 hauled coal in Northumberland for 50 years. The Liverpool to Manchester Railway competition in 1829 was won by George Stephenson, launching the railway mania era of the 1830s-40s when Britain's rail network expanded rapidly.
The document discusses the history and details of the Howrah Bridge in Kolkata, India. It was constructed in 1943 and was the only connector between Howrah and Kolkata until 1992. The bridge is a famous landmark and symbol of the city. It is a cantilever bridge that is 457.5 meters long and constructed out of 26,000 tons of steel. Maintenance of the bridge is handled by the Kolkata Port Trust and involves regular cleaning and corrosion prevention.
Howrah Bridge is a cantilever bridge built between 1936-1943 that connects Howrah and Kolkata. It was the longest cantilever bridge when completed and constructed without nuts and bolts using steel. The bridge experiences heavy traffic that causes pollution and overloading, though trams no longer run to reduce the load. Regular maintenance is required to address issues like damage from traffic, corrosion, and biological waste.
The Industrial Revolution began in Great Britain in the late 1700s and early 1800s, driven by factors like abundant coal resources, financial policies supporting innovation, and naval power. Key innovations included the steam engine, railways, and steam boats, which mechanized production and transformed transportation. New construction materials like cast iron, wrought iron, and glass facilitated larger industrial buildings and infrastructure. Major projects demonstrated new techniques, like the Crystal Palace exhibition hall built largely of iron and glass. The revolution dramatically altered architecture from decorative styles to plain, efficient designs and reshaped urban living conditions through new types of dense housing.
The document summarizes key developments in American industry and technology during the late 19th century. It describes the inconveniences of daily life before modern infrastructure like running water and electricity. It then discusses the completion of the transcontinental railroad in 1869, innovations like the air brake and telegraph that improved railroad safety and communication. Other topics covered include the growth of the telephone, light bulb, alternating current, Bessemer steel production process, and landmark structures like the Brooklyn Bridge.
The Ashtabula Bridge disaster occurred on December 29, 1876 when a railroad bridge collapsed as a train was passing over it. 92 people died, including passengers and crew, when the train plunged into the icy Ashtabula River below. An investigation found that the bridge had been improperly designed and inadequately inspected over its 11 years of use. The bridge's designer, Amasa Stone, had adapted an established wooden truss design for an iron bridge without approval from an engineer. The design flaws ultimately led to the bridge's failure under standard train loads.
This presentation was delivered to the HTAV annual conference 2012 and looks at key developments of the Industrial Revolution and how these ideas travelled to Australia during the Gold Rushes and transformed society there.
The London Underground, also known as the Tube, is the oldest underground railway system in the world. It has over 270 stations and 11 lines spanning more than 400 km. While the first underground train opened in 1863, much of the network was constructed over 100 years ago and requires extensive maintenance. Technological challenges included building tunnels near historical structures without damage and addressing water issues near the river Thames. The Underground also played an important role as a bomb shelter during World War II and its iconic map design helped popularize the system.
The document summarizes the history of the steam engine and several key inventions of the Industrial Revolution. It describes Thomas Newcomen building the first steam engine in 1712. James Watt then improved the design with a separate condenser. The document also outlines Richard Trevithick's invention of the first steam locomotive in 1803 and the Rainhill Trials competition won by George and Robert Stephenson's Rocket in 1829, demonstrating the effectiveness of locomotives. Finally, it mentions inventions like the spinning jenny and water frame that mechanized textile production and drove the Industrial Revolution.

The document provides details about the history, design, construction and facts related to the Golden Gate Bridge in San Francisco. It discusses how the bridge connects San Francisco to Marin County, spanning the Golden Gate strait. Key details include the bridge's length, height, weight, materials used, dates of construction milestones, and notable engineering aspects like its suspension and cable design. Statistics on deflection, load capacity, and quantities of concrete and steel used are also presented.
The document discusses the environmental impact of humanity throughout history from ancient times to the future. It covers several topics:
- The Agrarian Era from 4000 BC to 1st millennium BC, where early humans developed agriculture, writing, metals like copper and bronze, and domesticated animals.
- The Modern Era from the 1st millennium AD to the 21st century, bringing developments like the railway, steamships, internal combustion engine, airlines, and space exploration.
- The Digital age from the late 20th century focusing on topics like biotechnology, the internet, augmented reality, and a potential future Martian internet.
- The document concludes with predictions that internet connectivity will be ubiquitous,

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Editor's Notes
Good afternoon and welcome to this talk about the Great Western Railway and the train that thought it could. This talk could also be called John Whitton – the man who thought it could! Glenbrook railway cutting, no date, 12932-a012-a012X2448000091
For many years travel through the Blue Mountains was difficult. Cox’s Road to Bathurst was little more than a dirt track and it took at least two days for a horse and carriage to make the trip. The discovery of payable gold at Ophir in 1851 led to rising numbers of travellers on the road and the need for a railway was fast becoming evident but crossing the Blue Mountains by rail seemed like an impossible task. Image Soldier’s Gap, Mt Victoria, no date, NRS 4481.
And that task fell to the Chief Railway Engineer, John Whitton. The first railway line in NSW ran from Sydney to Parramatta and was opened on 26 September 1855. As part of the second phase of railway construction Whitton submitted plans in October 1860 for a railway from Penrith to Bathurst. The Great Western Railway would be 103 miles or 166 km long, include 17 tunnels and 33 stone viaducts, and cost 2 million, 650,000 pounds or 25 thousand,728 pounds per mile. The railway would, in most instances, follow the Great Western Highway. Image John Whitton NRS 4481 [4/8652 Image 1363]
Although Whitton’s plan for the railway line was practicable, it was in no way a certainty. Sir William Denison, the Governor-General favoured horse tramways and for a few years Whitton’s proposal was deemed too extravagant for the fledgling Colony. From this topographical map of the Blue Mountains from Lawson to Lithgow, you can see the terrain that Whitton was trying to avoid having to go up and down by his planned tunnels. In the end, Whitton had to compromise his original plans and opted to use zigzags instead of tunnels to reduce costs. By 1864 work began on the Great Western Railway and on 11 July 1867 the first 28 mile section from Penrith to Weatherboard (or Wentworth Falls) opened. Passengers then had to disembark and continue by coach to Bathurst. NRS 16407/1/2[16]
This first section of the Great Western Railway included some trademark Whitton structures. The Victoria Bridge, crossing the Nepean River at Penrith, was built at a cost of 96 thousand, 874 pounds. Whitton liked to build structures that would last. The iron girder sections were imported from England. Building the piers, that you can see on the contract plan on the right, and the assembly of the bridge fell to William Watkins, who was also contracted to complete most of the necessary earthworks from Penrith to Mt Victoria. The bridge originally took one railway line and a road across the River but was used as a road bridge from 1907 once the adjacent railway bridge was completed. The image on left is taken earlier than 1880 and you can clearly see workmen in the foreground. Victoria Bridge, digital id 15344_a044_000048 Contract plan from R560 [Box 7, W133]
This is a working plan on the approach to the Nepean River from Penrith. On the left hand side of the plan, below the word Penrith, is Jane St and above the word Penrith is High St or the Great Western Highway. Past Proctors Lane is the start of an easement down to the river. The very dark hand writing on the right with an arrow is the Log Cabin.

The Knapsack Viaduct forms an integral part of the Lapstone Zigzag. The viaduct, which can be seen in the distance in the photo on the left, crosses Jamison’s Creek, a deep sandstone gully. The sandstone arch bridge is a larger single track version of the viaduct in Picton. You can just imagine the railway winding upwards between huge rocks and bushland. A railway guide in 1879 described the viaduct as an admirable and imposing structure by the genius of John Whitton. Whitton himself described the viaduct in simpler terms as a bridge consisting of “five spans of fifty feet and two of twenty feet each, built in masonry … for a single line of railway on an incline of 1 in 10”. Quote http://www.environment.nsw.gov.au/heritageapp/ViewHeritageItemDetails.aspx?ID=4301012 Knapsack Viaduct at Lapstone, no date, digital id 17420_a014_a014000724 Knapsack Viaduct, earlier than 1880, digital id 15344_a044_000047
Just beyond the Knapsack Viaduct is the Lapstone Zigzag (or Little Zigzag), built on the eastern side of the Blue Mountains. Lapstone Hill summit is 526 ft (160m) and trains were required to reverse twice, on grades as steep as 1 in 33, to reach the summit, as you can see from the plan of the zigzag on the left. The zigzag was built on relatively light earthwork (compared to the Great Zigzag). From the plan on the left you can make out sections of the single rail line going backwards and forwards. The length of the top points and bottom points limited the length of trains and the single track meant that trains travelling in opposite directions had to stop at crossing points. A deviation with a tunnel was built in 1890 and in 1910 a new tunnel replaced the zigzag altogether.

Many of Whitton’s designs for railway stations across the Blue Mountains are strikingly similar. This is a contract plan for railway stations on the Glenbrook to Blackheath section of the GWR. The station design includes a ticket office, a general waiting room, and a Ladies Room with washroom attached. You can see many of these elements in photos of the early Blue Mountain railway stations that follow, especially the End Elevation on the right. R560/10 Blaxland Railway Station
These two photos of Glenbrook Railway Station, from around 1900, and Lawson Railway Station, in about 1910, show many similarities. Both stations have an island platform with the station and the veranda section in the centre. Glenbrook Railway Station, c. 1900, digital id 17420_a014_a014000729 Lawson Railway Station, c.1910, digital id 17420_a014_a014000736
And here is another similar railway station at Wentworth Falls. Again it has an island platform with a similar station design, which you can see in detail on the right. The photo dates from around 1900. Wentworth Falls Railway Station, c.1900, digital id 17420_a014_a014000760 R560/10 Wentworth Falls
The Weatherboard to Mt Victoria section of the Great Western Railway opened on 1 May 1868, less than a year after the first section of the GWR to Weatherboard opened. From Lapstone Hill the railway progressed along an escarpment, still climbing upwards through Leura, Katoomba, Medlow Bath and Blackheath. From Mt Victoria, the railway cuts across the Darling causeway, then through the Clarence tunnel and then down the second zigzag to the Lithgow Valley. The Lithgow Zigzag was completed on 18 October 1869 and began operating immediately. Mt Victoria Railway Station, c.1871, digital id 17420_a014_a014001367 R560 Box 11 Mt Victoria, Turntable, no date
Forced to use zigzags instead of tunnels due to budget constraints, the Great Zigzag or Lithgow Zigzag, remains an impressive monument to Whitton’s engineering skills. The Zigzag is a series of sloping tracks forming the letter “Z”, with reversing stations at Top & Bottom Points. It included three sandstone viaducts and two tunnels. While Whitton designed the zigzag, Patrick Higgins was contracted to build it and George Cowdery was the Resident Engineer. The Zigzag was bypassed by the ten tunnel deviation in 1910. NRS 16407/1/1[6] Great Lithgow Zigzag
For two and a half years between 600 and 700 men lived in tents up and down the zigzag. They were paid 1 shilling and 3 pence a day, and if the worker brought a horse to site he was paid 1 shilling and 9 pence. When the surveyors surveyed the line, they often had to be lowered over the cliffs in wicker baskets to shoot the line. Whitton supervised the construction from Engineer’s Lookout, a stone seat in a cutting next to No. 2 viaduct. Whitton had to send instructions by runners or use semaphore or mirrors to signal what he wanted. 3 man teams drilled holes in the cliffs with hand augers which were then filled with gunpowder for blasting. Two men held and turned the auger in place while the third man hit it with a hammer. Class Z1412 (G23) No.34 locomotive on the Lithgow Zigzag railway, no date, digital id 17420_a014_a014000453
The Great Zigzag descends the western escarpment from Clarence to the Lithgow Valley, a drop of 170m or 550ft. Between Top and Bottom points on zigzag is the middle road section, which descends 31m (101ft). Here you can see a plan on the left for Bottom Points and the photo on the right shows the platform and the pointsman residence. Both of these images are from around 1886.

One of the problems with the Great Zigzag was that the Top Points were too short. In 1901 a goods engine burst through the buffer stops at the Top Points Lookout and almost fell into the Ida Falls Gully, as can be seen by the dramatic photo on the right. The Zigzag, in general, could not cope with the increased rail demands which was creating bottlenecks. In 1908 work began on the ten tunnel deviation, which opened in 1910.

From the Lithgow Valley the GWR progressed over the Central Tablelands and arrived at Raglan, on the east bank of the Macquarie River by March 1873. It took nearly three years for the railway to continue to Bathurst though. Once again, Whitton had to design a bridge to cross a river, this time the Macquarie River. The wrought iron lattice girder bridge was constructed in 1876 and Bathurst Railway Station opened on 4 April 1876.

And here is Bathurst Railway Station. It is a Victorian Tudor style building and here you can see it from the proclaimed plan from 1875, to a shot taken soon after the station had opened and a present day photo of the station.

For John Whitton, the GWR remains a lasting memorial to his vision of what could be achieved if you think you can build it. “I think I can” became “I know I can” and in a relatively short space of time, 11 years, the GWR had crossed the Mountains and reached Bathurst. For the Blue Mountains and the settlements beyond, the railway meant faster travelling times for goods and produce and more growth and development. As NSW moved into times of prosperity, the Blue Mountains became a leisure spot. Guest houses and holiday cottages flourished alongside luxury hotels such as the Carrington and the Hydro Majestic. The Blue Mountains would never be the same again. 3673 on Caves Express Knapsack Viaduct, 1936, digital id 17420_a014_a014001371 Cover NRS 16407/1/2[30]
And finally, these last photos show how the Blue Mountains town of Katoomba developed. In the first photo, taken in about 1884, you can see the Railway Station in the foreground and the Carrington Hotel under construction, both surrounded by a rural setting. The photo below, from about 1892, shows a drastically altered new railway station but still surrounded by not much else. By 1930 though, there are a large number of buildings around the station, including the Carrington in the top right of the photo. The last photo, from 1950, shows a Katoomba that may be recognisable to many of you.
