Title: Analysis of Transverse Internal Force in Deck of Box Girder with Corrugated Steel Webs under Wheel Load
Abstract: For calculating the transverse internal force in bridge deck of box girder with corrugated steel webs under vehicle load,first,the wheel load is converted into half-sine load which distributed along the longitudinal direction,then,this continuous load is substituted into the frame analysis method model for box girders with corrugated steel webs to solve the transverse internal force of corresponding position.In order to verify the accuracy of this load conversion mode,the calculation value of calculation model is compared to measurement result and data of finite element analysis.It shows that the calculation value got by load form conversion can met the accuracy requirement compared to the measurement result and data of finite element analysis,and the differences are within 10%.Further numerical analysis of the calculation result under different loading conditions including different loading positions and different amount of concentrated wheel loads verified the feasibility of this load transfer form.Meanwhile,the method of effective distribution width in highway bridge specification is adopted to calculate the corresponding bridge deck transverse stress,the specification value is about 30%-40%larger than the abovementioned three kinds of result.
