摘　　要：为了确保框架填充墙结构在地震时具有良好的变形能力和耗能能力,减小填充墙体对主体结构的不利影响。通过对普通框架填充墙结构构造做法进行改进,设计了3榀1∶2比例的带缝填充墙框架试件,对试件在低周反复荷载作用下试验,分析研究了试件的承载能力、滞回性能、延性等抗震性能和破坏机理。并对不同竖缝宽度的试件进行对比分析,为带缝填充墙框架结构的深入分析研究和实际应用提供了理论基础。Seismic behaviors of three specimens of infilled frame structure with different vertical slit width whose scales were 1∶2,which were studied and compared under low reversed cyclic lateral loading in this paper.Emphasis was put on the evaluation of the failure mechanism,hysteresis loops,displacement ductility,deterioration of strength and stiffness and energy dissipation of the specimens under the seismic loads.This work provided a theoretical basis for the further study and practical application of infilled frame structures.
