Abstract
In bridge design, engineers strive to plan an economical structure that will safely
transmit loads to the ground without collapsing or deforming excessively. Since it is
difficult to predict the exact loading and circumstances that a bridge must withstand, all
bridge designs include a substantial margin of safety. Design standards vary throughout the
world, but all aim at ensuring that new bridges will provide many years of service and will
maintain an adequate margin of safety against failure.
Bridge design involves a number of design steps which involves tidious calculations
due to the presence of moving loads and needs choice of parameters and decision. So due to
the complexity and time consumeness of the design we will be better off if we use bridge
design programs to get better and accurate results in a short time. But the problem is these
programs are too expensive to buy and use. Using pyrated softwares is illegal and
immoral.And also using excel written programs has its own problems.
This project appreciates the application of home made (self made) programs to make
life easy and give a highlight on the procedure behind commercial softwares. This thesis is
concerned with developing Software for design of slab and T-girder reinforced concrete
bridges. The software is produced using Visual basic 6.0. The design is based on the
standards on ERA 2002 Bridge design manual. The program analyzes and designs only
Simple span slab and girder bridges and outputs in different forms are available. The user
manual and the video tutorials will show how to use the software simply. Finally,
conclusions and recommendations are made based on the produced software.
