摘要
对少内纵墙、底部设多层大空间多层R/C剪力墙结构体系的一栋16层1/18缩比模型振动台试验结果进行了分析,简述了模型振动台试验结果的破坏特征,比较了结构模型对3种地震波反应的差异,分析了位移、加速度反应的变化规律.结果表明,若设计得当,该体系的整体抗震性能较好;地震波的频谱特性是影响结构反应程度的主要因素之一;结构顶点加速度的动力放大倍数随结构刚度的退化而下降;弹、塑阶段振形变化不大.
The multi-story R/C shear wall structural system which has larger rooms in lower stories and fewer internal longitudinal walls has more aduantnges in using.In order to sutdy its seismic behaviofs,a 16-story 1/18 abed model is maal and tested on the shaking table.By data processing,the structural responses such as acceleration, displacements ate are discussed.From the tact results abtalned,it is shown thst the performance of model is very gab.No concentrated demase rain occures in the structure.
