Seismic response analysis of precast slab-on-pile bridge

Abstract

In this study, the seismic performance and energy dissipation capacity of slab-on-pile joints were investigated using numerical modeling. The results indicate that the static curve of the tubular pile under low-cycle lateral loading is complete and demonstrates good energy dissipation capacity. Under the action of random seismic excitations, the displacement of the slab-on-pile structure in one direction reached 0.023 m, which satisfies the code requirements. The improved slab-on-pile joints were applied in the nonlinear dynamic time-history analysis of the bridge structure.
