Fast construction of bridges using precast concrete elements provides benefits to both owner agencies and contractors. For owners, it reduces the duration of work zones, lowering traffic handling costs and accident risks while causing less inconvenience to the public. Contractors benefit from reduced hazards, the ability to accomplish more work in less time with fewer weather delays, and lower costs. Examples are given of bridges constructed rapidly using precast concrete piles, pile caps, piers, abutments, beams, and other elements.
Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading.

Effect of Static Load on Cast Iron Drainage Manhole Coverijtsrd
Drainage manhole covers are widely used in sanitary sewer and storm water systems in world. However, technical information regarding their structural aspects is limited. The main objective of this paper is to evaluate the effect of main parameters that impact the design of manhole cover. A three-dimensional finite element model for circular manhole cover was developed using AutoCAD, solid works and NX. The 3d model was analyzed by ANSYS for different parameters like different load and different material. Here cast iron is used as material of cover. The load condition was applied for two type of cover one without stiffer and with stiffer. Dhruvkumar Joshi | Hardik C.

A Study on Design and Analysis of Precast Box for Road Bridge Construction us...ijtsrd
Transportation always plays an important role in economic growth and globalization for a country. Road transportation is one of the main transporting way in India. Therefore it requires connectivity of cities. Hence bridges and culverts are constructing to connect Roads.Box Culvert can be defined as a structure having box shape which is constructed below the embankment to drain water from one side of the bank to the other side of the bank. Failure reasons of a Box Culverts are maintenance failure, erosion and increase in scour depth, and Installation Failures. To improve the problems occurring in the Structure are described briefly. Box Culverts are normally constructed without RCC cut off and curtain walls. Due to which structure gets damaged easily. In previous researches Box Culvert are constructed with PCC cut off and curtain walls while taking various parameters in design. Movements of people and transportation will not be affected because structure will not be constructed number of times because life of structure will be very long. Seepage pressure is less in box culvert with RCC Cut off and curtain walls because the gripping in RCC structure is good as compare to PCC Structure, and Seepage pressure is directly proportional to voids that makes PCC structure unstable against seepage pressure. BM of PCC walls is also less than as compare to RCC walls. Life of structure will also increase around two times, and also Government planning will not be affected because project will be for long time period. In designing of structure the two major factors should be kept in mind i.e. economy and safety. If the load is overestimated than the structure will be uneconomical whereas if the load is underestimated the safety of structure will be compromised. Hence the calculation of load and their combination should be done very precisely The study included estimation of PCC and RCC Cut off and Curtain walls through comparative results in SOR 2017.

Design and Analysis of a Girder Bridge for Highway Structures Using Sap 2000ijtsrd
In this study, a comparative study supported two differing types of bridges i.e. Deck type and Pre stressed deck type using finite element analysis in SAP 2000 is ready , considering same loading class 70 R as per I.R.C. loading. During this study well also prepare a price analysis of both the structures using S.O.R. C.P.W.D. 2014. This sort of bridges is more preferred when it involves connectivity to short distances. So, its necessary to update the analysis and style methods. Here, during this paper, theres an effort to review the comparison of maximum bending moment thanks to super load during a girder and slab bridge an equivalent bridge is analyzed as a three dimensional model in finite element software as SAP2000, apply an equivalent loading finished conventional methods and compared the results. The utmost bending moment results obtained from finite element model.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

to a report by the Texas
Transportation Institute, costs
incurred by drivers passing
through a work zone (along with
engineering costs) can be $10,000
to $20,000 per day. A recent
Federal report indicates user
