为考核某实际背栓式微晶幕墙的抗震性能,将典型幕墙单元安装于试验钢框架上,进行模拟地震振动台试验。通过对幕墙单元的加速度反应、位移反应、面板应变变化情况及自振频率等变化规律的分析和研究,并结合试验现象,评价被试幕墙单元的抗震性能,为实际幕墙工程提供试验依据,提出改进措施。此外,对建筑幕墙抗震性能考核指标和方法提出建议,供进一步研究参考。 In order to evaluate the seismic performance of an actual back bolt type microcrystalline curtain wall, a typical curtain wall unit is installed on the test steel frame to simulate the earthquake shaking table test. Based on the analysis and research of the variation law of the acceleration response, the displacement reaction, the change of the panel strain and the natural frequency of the curtain wall unit, and combined with the test phenomenon, the seismic performance of the curtain wall unit is evaluated, and the experimental evidence is provided for the actual curtain wall project. improvement measures. In addition, the curtain wall seismic performance evaluation indicators and methods to make recommendations for further study and reference.
