中文摘要

选用四川汶川卧龙地震波等,通过模拟地震振动台试验,测试了“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动力特性,及其在8度多遇、8度基本和8度罕遇水准烈度地震作用下的阻尼比、频率变化和顶层位移。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。

英文摘要

In this study, Wenchuan Wolong seismic wave, etc. were selected, and the shake table test on ‘tie column + ring beam + cast-in-place slab’ recycled aggregate concrete (RAC) masonry structure was conducted. Not only the dynamic characteristics of structure, but also the damping ratio, frequency changes and the top floor displacement 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 suggested by the 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 good seismic behavior and can resist the earthquake action under each level of fortification intensity in the location. It is concluded that RAC masonry structures can be promoted in the earthquake hit-area reconstruction.
