摘要:
在结构设计中,填充墙通常被当作非结构构件,不参与结构抗震计算。在实际地震作用下,填充墙和框架成为整体,共同抵抗地震作用,合适的墙-框连接方式可以减轻二者的相互作用,从而提高结构整体抗震性能。首先,运用ABAQUS软件对前人已开展的考虑墙-框不同连接方式的框架结构拟静力试验进行数值模拟,验证了所建立的有限元模型的可靠性。然后,基于某典型框架结构,建立三种墙-框连接方式的框架结构有限元模型并进行分析。模态分析表明,墙-框连接方式对框架结构的振型及周期影响较小,结构动力特性趋于一致。通过多遇地震和罕遇地震下的弹塑性时程分析,对比分析各结构的加速度反应、位移反应、滞回耗能及构件震害特征等可知,合理的墙-框连接方式可以提高结构抗震性能。针对本文框架结构工程实例,采用墙-框脱开密封材料封缝,构造柱加水平系梁的连接方式时其抗震性较好。
Abstract:
Infilled walls are treated as nonstructural components which don’t participate in seismic calculation in structure design. In fact, filled wall and frame resist seismic action together. Suitable connection way between them can reduce the interaction, which can improve the structural seismic behavior. ABAQUS is adopted to simulate the pseudo-static test considering connection ways between infill wall and frame, and the reliability of finite element model is verified. The finite element models of the structure with different connection ways are established. Modal analysis shows that connection way has small influences in structural mode shapes and cycles, and the structures show the same dynamic properties. By analyzing the elastic-plastic time history of the structures in frequent and rare earthquake, acceleration response, displacement response, hysteresic energy and component damage characteristics show that the appropriate connection way can improve seismic behavior of structures. In the case of this dissertation, the way of constructional column and horizontal beam between filled wall and frame contribute has a better seismic behavior.
