Analysis of Seismic Response and Influencing Factors of Upper-lower Segmented Prefabricated Box Culverts
摘要
Abstract
To address the insufficient research on the seismic response of typical upper-lower segmented prefabricated box cul-verts,the nonlinear time-history response analysis method was used to analyze the effects of connection form,joint position,and soil shear modulus on the seismic response of box culverts.The results show that the lateral seismic response of upper-lower segmented prefabricated box culverts is similar to that of monolithic prefabricated box culverts,but their deforma-tion modes are slightly different.When the joint is located at one-half of the height of the sidewall,the deformation and stress of the box culvert are moderate,and the seismic performance is relatively balanced.The seismic response of box culverts in-creases with the increase of soil shear modulus.关键词
