不同转换梁形式对隔震装配式联肢墙结构受力性能的影响
The Influence of Different Transfer Beam Forms on the Mechanical Performance of Isolated Assembled Coupled Wall
摘要
Abstract
This study further studies the seismic performance of prefabricated concrete joint shear wall structures with base isolation in the previous period.The effects of different transfer beam forms on the structural damage mode,hysteresis curve,energy dissipation performance,sleeve stress and bearing surface pressure are analyzed.The results showd the bearing capacity of the base-isolated assembled concrete coupled shear wall structure has little difference and shows good energy dissipation performance by using different forms of transfer beams.The separated transfer beam changes the damage mode of the superstructure and improves the energy dissipation performance of the coupling beam.The use of steel plate to reinforce the transfer beam avoids the occurrence of damage at the transfer beam,and provides a fixed end with greater stiffness at the bottom of the wall limb,thereby reducing the damage of the wall limb and effectively protecting the main wall.However,it should be noted that both the separated transfer beam and the steel plate reinforced transfer beam would cause an increase in the stress of the sleeve in the superstructure.Among them,the stress of the steel bar in the PCSW-2 structure with the separated transfer beam has a greater increase.In addition,the rotation angle of the PCSW-2 isolation layer and the tensile stress of the support also have an increasing trend.These factors should be fully considered in the design process.关键词
