Optimization Design of the Inner Lining Concrete Parameters for Large-span PC Continuous Rigid Frame Bridge with Corrugated Steel Web
The waveform steel web composite beam bridge has gradually become a new direction for the development of large-span bridges because of its accordion effect.In order to study the influence of lining concrete parameters on the shear performance of waveform steel web prestressed concrete(PC)continuous rigid frame bridges,ANSYS software was used to establish a finite element model of waveform steel web PC continuous rigid frame bridges.The accuracy of the model was verified by comparing measured data with numerical simulation data.The influence of lining concrete parameters on the shear force and shear ratio was studied.The research results indicate that the ap-propriate values for the length,thickness,and thickness change rate of the inner lining concrete are 9.5 m,0.5 m,and 0.3 respectively.The relevant conclusions can provide reference for the design and construction of large-span corrugated steel web PC continuous rigid frame bridges.
