采用填充墙—框架并联模型分析了填充墙对结构刚度的贡献,填充墙刚度效应对结构自振周期的影响,并对多工况下的框架结构填充墙结构进行了八度多遇地震作用下的时程抗震验算。通过分析认为,填充墙的刚度效应使结构的自振周期减小,填充墙的不当布置使结构在水平地震作用下产生较大的层间位移而出现薄弱层。在结构设计中,有必要根据填充墙实际状况考虑填充墙对结构体系的刚度效应,使框架填充墙结构体系在地震作用下的计算更切合实际。
The infilled wall-frame parallel model was used to analyze the contribution of infilled walls to the structural stiffness and the effect of infilled wall stiffness on the natural period of the structure. Under the earthquake of octave, Time-course seismic checking. The analysis shows that the stiffness of the infill wall reduces the natural period of the structure, and the improper placement of the infill wall causes the structure to produce a large interlayer displacement and a weak layer under the horizontal seismic action. In the structural design, it is necessary to consider the stiffness effect of the infill wall to the structural system according to the actual situation of the infill wall, so that the calculation of the frame infilled wall structure system under the earthquake action is more realistic.
