摘要
填充墙的竖向不规则布置会对框架结构产生不利的影响。采用等效斜撑建立了基SAP2000的三种填充墙竖向不规则布置的等效模型,从结构的整体位移响应和破坏机制等方面对其进行了分析。结果表明,填充墙竖向不规则布置易导致结构薄弱层的凸显;填充墙对结构塑性铰的发展有一定的抑制作用,其竖向不规则布置会使得结构的塑性变形在薄弱层集中发生。针对以上分析,对地震响应最大的模型的竖向不规则布置提出改进方案,并通过pushover分析进行了有效性验证。
Vertical irregularities of the infilled wall have adverse effect on frame structure. Three kinds of equivalent models of the infilled wall with vertical irregular arrangement were established by SAP2000 according to the equivalent diagonal bracing and comprehensive analysis was done in aspect of the overall displacement response and failure mechanism and so on. Results showed that vertical irregularities of the infilled wall easily led to highlight of structure weak story. Development of plastic hinge of the structure was restrained by the infilled wall to a certain extent. Vertical irregularities of the infilled wall would make the plastic deformation of the structure mainly occur in the weak story. Based on the above analysis, an improved solution to vertical in＇egularities of the infilled in models of the maximum seismic response was put forward and effectively verified by a pushover analysis.
