Parametric study on t-beam bridge

The infrastructure available in a country judges the development of that country. Highway which allows the flow of human beings and material is a major part of infrastructure. Tee-beam bridges forms the major proportion of bridges constructed on the highways. IRC codes are developed and reused from time to time based on the research work carried out all over the world. IRC 112-2011 replaces two codes of practice IRC 21-2000 and IRC 18-2000. Also IRC 112-2011 introduces limit state method of design of RCC bridges. Single span two lane bridge is subjected to IRC class AA tracked loading by varying the span is analyzed using software VB6.0. In this study parametric studies are conducted on various bridge super structural elements. The study is mainly focused on the economical depth of a longitudinal girder for different span. Nomograms are also developed which can be used as a handy tool in the design of T- Beam Bridge
