Abstract:
One model test beam is made to study effective distribution width of the deck of girder with corrugated webs. Then static non-destructive testing is conducted to study distribution of transversal force of this structure. And by combination to the current road bridges criterion value and data of finite element analysis, on the basis of comparetion of three kinds of effective distribution width values, the road bridges criterion value was modified and the effective distribution width correction coefficient under different loading conditions was obtained. And the results demonstrated that the road bridges criterion value was smaller than test results and data of finite element analysis, in order to apply to the effective distribution width calculation of box girder with corrugated steel webs, the former should be multiplied by the coefficient of more than 1.0.
