Analysis for Shear Lag Effect during Construction of Box Girder Cantilevers of Large-span Continuous Rigid Frame Bridges

Tao Li

Abstract

This paper computes and analyzes shear lag coefficient of main control section during construction of cantilevers of large-span pre-stressed concrete single-box chamber rigid frame bridges by means of finite element software.The results of analysis show great significance for test and control of stress during construction of bridge cantilevers and can provide a reference for design of bridge of the same kind.
