Study on Ductility Aseismic Design Method of Urban Viaduct
Aseismic design of bridge is one of the key points in the viaduct design,which plays an important role in the design of bridge substructure.Due to its advantages of economy,durability,reliability and convenient construction,the ductility aseismic design method plays an important role in the aseismic design of viaduct.Therefore,it is necessary to summarize and further study the ductility aseismic design method and ideas.Based on an engineering example,a conceptual design idea of ductility aseismic design for urban viaduct is given.An aseismic analysis model is spatial beam element is established by the finite element method to summarize the checking calculation method of each component under earthquake action,and study the applicable conditions of seismic ductility,which provide reference for the aseismic design of similar projects.
