摘要
将某高层建筑外层吊挂式玻璃幕墙的地震作用分为三种模式进行描述,即加速度模式、位移模式和内力模式。通过楼面频谱分析,拟合楼面加速度包络反应谱,根据楼面包络谱生成具有广泛意义的楼面加速度时程波形;根据主体结构的最大层间位移角确定幕墙系统的最大平面内位移;通过建立幕墙系统的有限元模型进行弹性时程分析,提取吊杆内力的最值。对该幕墙系统进行振动台试验来验证该方法的合理性,并对试验结果进行了分析和评价。
Seismic responses of outer hanging glass curtain wall for a high-rise building are divided into three kinds;acceleration,displacement and internal force.By analyzing floor acceleration spectrum and fitting the floor acceleration envelope response spectrum,typical floor acceleration time histories can be generated.The maximum plane displacement of curtain wall system can be determined according to the maximum layer displacement angle of the main structure.The maximum internal force of the boom can be obtained through the elastic time history analysis by using the finite element model of the curtain wall.Shaking table tests were conducted to verify the reasonableness of the method.
