Analysis on Stress Performance of Prestressed Concrete Bridge Pier
In order to improve the design level of urban bridges,this paper takes Pudong North Road branch river No.1 bridge as the research object,calculates the vertical load,automobile braking force and temperature force acting on the bridge structure,and analyzes the stress of the bridge pier cap beam under the normal use limit state,persistent state,and transient state.At the same time,the calculation model is established by using Dr.Bridge software and Midas Civil software,and the shear force of the bridge pier body under the action of E1 earthquake is calculated.The research results can be used for reference in the design of similar prestressed concrete bridge piers.
