摘　　要：为了研究带缝空心钢筋混凝土剪力墙结构房屋的动力特性,进行了缩比为1∶3的6层模型房屋的动力特性试验及拟动力试验,获得了结构的周期、振型、阻尼比、动力放大系数等动力特性参数。在试验研究的基础上,利用有限元分析软件ANSYS对结构模型进行了模态分析,试验结果与ANSYS模拟结果吻合较好。研究结果表明,带缝空心钢筋混凝土剪力墙结构是一种介于框架结构和传统剪力墙结构的新型结构形式。In order to study the dynamic properties of reinforced concrete silt hollow shear wall building, the dynamic characteristics test and pseudo-dynamic test of 1/3 scale model of 6-story building were made. Dynamic property parameters such as periods, vibration modes, damping ratios, the amplificatory coefficients of seismic action were obtained. On the basis of the experimental study,the software ANSYS was adopted to make modal analysis. The results show that reinforced concrete silt hollow shear wall structure is a new form of structure which is between frame structure and traditional shear wall structure. The experimental results accord with ANSYS simulation results well.
