Static Pushover Performance of a Novel Prefabricated Laced High Pier with CFST Columns and Precast RC Tie Plates
摘要
Abstract
A novel prefabricated concrete filled steel tube(CFST)laced pier system connected by discontinuous precast RC tie plates is proposed,providing high lateral stiffness and high construction efficiency.Refined finite element models are established using ABAQUS to evaluate the static pushover response of the system and to clarify its damage patterns.A parametric study is conducted to quantify the effects of tie plate arrangement,including spacing,height and distribution ratio.Based on the finite element analysis,several concept design suggestions of the pier system are put forward.The results show that the pier system has high lateral stiffness,bearing capacity and ductility,and the novel prefabricated CFST column-RC tie plate connection can ensure the efficient force transmission and full deformation of the system.At peak load,the connections exhibited only localized yielding,suggesting a rational connection design.Reasonable design of the height and spacing of the RC tie plate can change the plastic development mechanism of the system to meet the different performance-based design demands.关键词
