Optimization of Box Girder Bridge Using Genetic Algorithm Method
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 3
Abstract
Box girder is widely used in bridge engineering because of its economy, aesthetic appearance. Now a day it is easy to get safe design due to recent advances in design field but safety with economy is the basic need of present generation, hence it is necessary to go for optimum design. In large span bridges pre stressed concrete is adopted. And thus in present study PSC box girder of span 40m is used for the study. And the loadings are taken as per Indian Road Congress loadings (IRC:6-2014) pre-stressed concrete code (IS:1343- 2012) and IRC: 18-2000 specifications. The box girder is designed by limit state method. A computer programme is written in MATLAB-CSI API software for optimization process using genetic algorithm method, and analysis results are retrieved from CSI bridge software to carry out optimization process.
