摘要
针对砌体填充墙框架结构在地震作用下的受力特点,结合汶川地震,分析了填充墙框架结构产生震害的主要原因。建立了填充墙简化分析的等效双压杆模型。着重研究了地震荷载作用下,填充墙对框架性能的影响。结果表明,砌体填充墙对提高结构的抗侧刚度和强度有一定的作用,改变了框架结构塑性铰的分布和发展水平。同时也表明,砌体填充墙在地震作用时有一定的耗能能力。
According to the Wenchuan Earthquake and the seismic resistance of an infilled frame under strong earthquakes, the main reasons for earthquakes damage to infilled frame structures are analyzed. Infilled wall is simplified into equivalent double compressive strut model. An investigation has been conducted to study the influence of infill walls on the performance of the framework subjected to earthquake （dynamic） loading. The study shows that masonry infill walls improve the structure＇ s lateral stiffness and strength, and also have a capacity of dissipating energy when subjected to earthquake （dynamic） loading.
