Abstract: A novel spatial grid model is proposed and applied to analyze the shear lag effect of six tower cable-stayed bridge. The theoretical principle of the proposed spatial grid model is elaborated along with the relevant illustrations of the modeling parameters of the composite box girder with corrugated steel webs. Then, the typical transverse and longitudinal shear lag coefficient distribution patterns at the key cross sections of side-span and mid-span are analyzed to provide reference for simple bridges. The effectiveness and accuracy of the proposed spatial grid analysis method is validated through cable-stayed bridge.

Key words: road engineering, shear lag coefficient, cable-stayed bridge, space mesh analysis method, corrugated steel webs, composite beam bridge
