摘要
某六层砌体结构采用橡胶支座与叠层橡胶滑板支座并联组合作为隔震层。考虑到振动台的性能及砌体结构模型试验的特点,从某砌体结构中提取部分结构作为等代结构,满足原整体结构作用及效应相似的要求;然后对等代结构进行缩尺模型设计、制作与试验。试验分为隔震和非隔震两阶段,通过对比其动力反应,由模型试验结果分析原型结构的抗震性能,并将试验结果与数值模型分析结果进行了比较,表明该隔震结构试验较好地揭示了隔震结构的反应特点,采用"等代结构"进行模型振动台试验是合理和有效的。
Isolator layer combined with rubber bearings and laminated rubber sliding bearings was applied to a six-story masonry structure. For the restriction of the shaking table＇ s performance and the particularity of masonry structure model test, a substitute structure was developed to represent the original masonry structure, which should meet the similarity of actions and effects between them, then a scaled model which simulate the substitute structure was designed, manufactured and tested. The test was performed in two phases--with isola- tor and without isolator. By comparing both dynamic responses, analyzing the seismic performance of the origi- nal structure through model test results, and comparing the calculated data by software with the test data, it was proved that the responses of the isolated model are satisfied, and the approaches for the ＂Equivalent Structure＂ model test are reasonable and effective.
