| Abstract: | The fundamentals of elastic analysis are given with the computer science program available, and the parametric analysis on shear lag effect of the box girder bridge is presented. The parametric studies include statically determinate structure, width span ratio, the variation of shear lag coefficient on fixed end section and width depth ratio. Section configuration, cantilever length and loading form are also taken into consideration. Shear lag coefficients along the span are studied on straight line, parabolic as well as constant depth section along span. Some conclusions are drawn on this study. |
