A Simulation Analysis of Seismic Torsional Response of Prefabricated Reinforced Structures with Existing Framework on High-Slope
CHENG Qiuyue
Abstract：This study analyses the seismic torsional response of prefabricated reinforced structures with existing framework on high-slopes,focusing on the impact of the torsional response on the stability of the connection parts of prefabricated structures.Based on a specific high-slope engineering project,the high-slope environment was simulated using actual rock mass data.Rayleigh damping was used to add overall damping,and a dynamic stiffness matrix was used to add shear elements.A numerical model of the prefabricated reinforcement structure with the existing framework was then established using the finite element flexibility method to add beam column elements.The results showed that the displacement deformation of the prefabricated reinforced structure with an existing frame under seismic torsional response was mainly in the middle layer,while the displacement deformation in the upper layer was relatively small.The main reaction area was located at the top of the slope and in the backfill area.The seismic torsional response of the existing frame-assembled reinforced structure on the high slope exhibited excellent elastic-plastic hysteresis characteristics under earthquake,suppressing the transmission of seismic forces and controlling the sliding instability of the high-slopes.
