Pre-Cast Technology: An Initial Step to Sustainable Developmentijsrd.com
Erection of precast construction unit is a complex mechanized process for continuous assembly of buildings and installation of prefabricated elements and components. Precast construction provides advantages over conventional practice by costing the pre definite size of the members (penal, walls, beams, columns) in the factory. In this technique the structural members specially made of concrete that has been cast into form prior being transported to its construction location for the final installation work. Precast construction technique is the first step to satisfy the demand of sustainable housing for the population in developing country. It is also one of faster construction process which also provides high quality. This Paper cover different types of precast construction system, its main features, equipment required for the construction work and its installation process for different type of components.
Comparitive study on rcc and composite (cft) multi storeyed buildingseSAT Journals
Abstract In India reinforced concrete structures are mostly used since this is the most convenient & economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. So the structural engineers are facing the challenge of striving for the most efficient and economical design solution. Use of composite material is of particular interest, due to its significant potential in improving the overall performance through rather modest changes in manufacturing and constructional technologies. Steel-concrete composite columns are used extensively in modern buildings. Extensive researches on composite columns in which structural steel section are encased in concrete have been carried out. In-filled composite columns, however have received limited attention compared to encased columns. In this study E-Tabs nonlinear software is used for simulation of steel concrete composite (CFT) with steel reinforced concrete structures (RCC) of G+14, G+19 and G+24 stories each are considered for comparative study. Comparison of parameters like time period, storey displacement and storey drift is done. Keywords: Composite CFT columns, bracings, shear wall, time period, storey displacement and storey drift.

The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Introduction
Building construction is an ancient human activity. It
began with the purely functional need for a controlled
environment to moderate the effects of climate.
Constructed shelters were one means by which human
beings were able to adapt themselves to a wide variety
of climates and become a global species
3. Precasting/Prefabrication
• Prefabrication is the process of assembling components of a
structure in a factory or other manufacturing site and transporting
these complete or sub assemblies to the construction site.
• The work is carried out in two stages.
1. Casting, curing
2. Transportation and erection in process
6. Concept of Precasting
1. Producing large quantity of structure and shipping them to
site
2. Independent of weather condition
3. Hardened before being used on site
4. Casted according to the required size and shape
5. Casted in the factory conditions or controlled weather
6. Casted in the moulds
7. Precast Components
• Precast beams
1. Internal beams
• support for the slab on the both sides
• Used Internally
2. External beams
• Support for the slab only in one side
• Used on the edges of structure.
13. Precast Construction System
1. Large panel system(fig.1)
2. Frame system(fig.2)
3. Slab column system(fig.3)
Fig.(1) Fig.(2) Fig.(3)
14. Connection between precast
components
There are three types of connection to
connect precast component with each other.
1. Column to column connection.
2. Beam to column connection.
3. Slab to beam connection.
15. Column to column connection
Metal bearing plates and embedded anchor bolts are cast into the ends of the columns.
After the columns are mechanically joined, the connection is grouted to provide full
bearing between elements and protect the metal components from fire and corrosion.
16. Beam to column connection
Beams are set on bearing pads on the column corbels. Steel angles are welded to metal
plates cast into the beams and columns and the joint is grouted solid.
17. Slab to beam connection
Hollow core slabs are set on bearing pads on precast beams. Steel reinforcing bars are
in inserted into the slab keyways to span the joint. The joint is grouted solid. The slab
may remain untopped as shown, or topped with several inches of cast in place concrete
19. Why precast not cast in situ ?
• Quality can be controlled and monitored much more easily
• Weather is eliminated as a factor-you can cast in any
weather and get the same results
• Less labour is required and that labour can be less skilled
• On site, precast can be installed immediately
• The precast structures can be dismantled, when required
and they can then be suitably used elsewhere.
