摘要
为研究双向地震作用下预制板砖砌体房屋结构的抗震性能评价方法,进行1∶2比例模型的双向拟动力试验。通过介绍试验中结构刚度和频率的变化,提出基于频率变化的抗震性能评价方法,评价结果与基于刚度退化的方法接近,但计算过程更加简捷。基于频率的评价结果与实际破坏状态也较吻合,说明该方法可以应用于预制板砖砌体房屋结构的抗震性能评价。
In order to study the seismic performance assessment method of brick masonry structures with precast slabs, the bi-directional pseudo-dynamic test of 1∶2 scaled building model was carried out.The change of rigidity and frequency of the structure was introduced in the test, and a seismic performance assessment method based on frequency was presented. The evaluation results based on frequency were very close to those based on rigidity, and frequency-based method had a simpler calculation process, and the results were also closed to real damage condition.Therefore, the frequency-based method could be applied in seismic performance evaluation of brick masonry structures with precast slabs.
