Research on Seismic Response of Box Culvert Structures Based on Variable Parameter Models
Facing the problem of seismic performance analysis of box culvert structure of traffic bridge in water conservancy project,this paper selects the box culvert in the third bid of the comprehensive management of water system in the west bank of Pihe river(Phase II)project(the second batch),analyzes its box culvert structure,constructs a finite element model,sets up a variable parameter model,and analyzes the influence of detailed structure on the seismic response of box culvert structure.The results show that the reinforcement of the top plate and the reasonable setting of the increase interval of axillary angle size will promote the box culvert structure to obtain greater monotonic loading force and improve its seismic performance.When the horizontal displacement is 8.79mm,the horizontal load of test body 2 is 108.78kN,which is 8.57 kN larger than that of variable parameter model 3.The research method will promote the optimization of seismic design of box culvert structure.
