装配整体式剪力墙模型结构振动台试验研究
Shaking table test on monolithic precast concrete shear wall model structure
摘要
Abstract
In order to study the seismic behavior of monolithic precast concrete shear wall structure,a 12-story 1/5 scale monolithic precast concrete shear wall model structure was designed and constructed.The dynamic characteristics,acceleration magnification factor,floor shear and displacement,and the maximum inter-story drift were examined through a shaking table test considering three seismic waves.The cracking phenomenon was also studied in detail.The experimental study shows that after the first loading stage the natural frequency is reduced to 80％ of the original frequency.With increase in PGA,the natural frequency and the acceleration magnification factor are reduced,and the floor shear is increased.In the inelastic performance stage,evenly distributed horizontal cracks are observed of the junctions between the prefabricated wall and the floor.In addition,the model structure shows evidently nonlinear behavior,where the inter-story drift ratios increase and the natural frequency decreases significantly.By examining the peak inter-story drift ratios response,it is concluded that the monolithic precast concrete shear wall structure could be used against seismic intensity 8.However,the connection performance of the prefabricated wall and the floor should be strengthened to avoid through cracks.关键词
