摘要
为了满足工程实际应用需求,提高结构韧性,提出了两种设置柔性装置的填充墙连接方法,采用柔性装置将填充墙与主体框架结构连接,以改善附加填充墙框架结构的抗震性能。通过对1个框架试件和2个附加填充墙的框架试件进行低周往复试验,对比分析柔性装置连接下附加填充墙的框架结构的抗震性能。试验结果表明:柔性装置能够使填充墙与框架结构中的构件变形协同,减少二者之间的相互挤压或拉伸,降低填充墙的塑性损伤,附加填充墙的框架结构峰值荷载提高17%~21%。并基于有限元软件ABAQUS建立结构精细化数值分析模型,结合试验结果验证有限元模型的正确性。
In order to meet the requirements of practical engineering applications and strengthen structural resilience,two connection methods for infill walls with flexible devices were proposed.By the proposed flexible devices,infill walls were connected to the main frame structures to improve the seismic performance of the frame structures with infill walls.A comparative analysis of the seismic performance of frame structures with infill walls under flexible device connections was conducted through low cycle reciprocating loading tests on one bare frame specimen and two frame specimens with infill walls.The experimental results show that flexible devices can improve the interaction between infill walls and the main frame structures,reduce the plastic damage of infill walls,and increase the peak bearing capacity of the frame structures with infill walls by approximately 17%-21%.Furthermore,a refined numerical analysis model was established using the finite element software ABAQUS.The accuracy of the established numerical model was validated with the experimental results.
