| Abstract: | The shear lag effect in the composite box girder with corrugated steel web and the influence of major structural parameters on it were studied with 3-D fi nite element analysis, and the reliability of research results was confirmed by the model experimentation.After that, the practical calculating formula and cha rt were put forward for calculation of the shear lag coefficient in the composit e box girder with corrugated steel web; The research results will also provide the theoretic basis for improving the calculating system about the shear lag ef fect of composite box girder in the code. |
