摘　　要：为研究石材幕墙的抗震性能和破坏特征,以阿尔及利亚大清真寺南区石材幕墙工程为背景,设计了两组1:1振动台试验模型,通过振动台试验研究总结出了石材幕墙结构的地震响应特性,在此基础上,给出了石材幕墙结构动力特性简化模型,并通过引入相应的质量修正系数,得到震损石材幕墙结构自振频率计算公式。研究表明:结构自振频率在挂件和石材出现松动与损伤后逐渐降低;石材加速度响应受挂件位置和尺寸影响较大;石材与挂件之间的间隙增大了石材的加速度响应,但同时也减小了挂件的内力需求。Based on the stone curtain wall project in Great Mosque of Algiers,the seismic performance of the stone curtain wall was studied with two sets of 1:1 scale shaking table test.The quality correction coefficient was introduced to simplify the model of the stone curtain wall to solve the natural frequency after the damage of the wall.The results showed that the natural frequency is reduced after the looseness and damage of the pendant and the stone;the acceleration response is greatly affected by the position and size of the pendant and there is a certain gap between the stone and the pendant,which increases the acceleration response of the stone,but at the same time reduces the internal force requirement of the pendant.
