ANALYSIS OF THE INFLUENCE OF PREFABRICATED TIE BEAMS ON THE SEISMIC PERFORMANCE OF DOUBLE-COLUMN PIER UNDER DIFFERENT CONNECTION FORMS
In order to study the influence of different connection schemes of prefabricated tie beams on the seismic performance of double-column pier,the substructure model of the prefabricated tie beams of Xiaobicun bridge belt was established by using ABAQUS software.The section form and joint connection mode of the prefabricated tie beams were changed,and three finite element models were established.The pseudo-static analysis was carried out by displacement loading.The seismic and mechanical properties of prefabricated tie beams are studied from three aspects.The results show that the structural seismic performance of prefabricated tie beams varies with different section forms and joint connection modes.The connection scheme of"weld-double H-beam"has better seismic performance and deformation resistance.The optimal scheme should be selected considering the cost,construction requirements and construction methods in practical engineering.
