摘　　要：选用四川汶川卧龙地震波等,通过模拟地震振动台试验,对"构造柱-圈梁-现浇板"体系再生混凝土砌块砌体房屋结构模型的抗震性能进行了研究,分析其在8度多遇、8度基本和8度罕遇水准烈度地震作用下的动力特性、试验现象以及动力反应。试验及分析结果表明,模型在8度多遇和罕遇水准烈度地震作用下的最大层间位移角均小于建筑抗震设计规范规定的层间位移角限值,墙体出现小裂缝;说明"构造柱-圈梁-现浇板"体系再生混凝土砌块砌体结构的整体抗震性能较好,能够抵抗所在地区设防烈度下各水准地震作用。再生混凝土砌块承重结构可以在地震灾后重建地区推广应用。The shake table test on ＇tie column-ring beam-cast-in-place slab＇recycled aggregate concrete（RAC） block masonry structure was conducted with Wenchuan Wolong seismic wave.Not only the dynamic properties of structure,but also the test phenomenon and the dynamic response of the model under intensity 8 of frequently occurred,basic and seldom occurred earthquake were tested.On the basis of test results,the model＇s maximum drift angle under three occurrences was respectively less than the allowable value of earthquake resistant structure recommended by the Chinese Code for Seismic Design of Buildings.Tiny cracks were found on the wall,however it showed RAC masonry structure constrained by ＇tie column ＋ ring beam＇system exhibited a good seismic behavior and was able to resist the earthquake action under each level of fortification intensity in the location.It is concluded that RAC masonry structures were able to be promoted in the earthquake hit-area reconstruction.
