摘要
为了研究带缝空心钢筋混凝土结构房屋的动力特性,进行了1∶3.0模型6层结构房屋的模态试验及拟动力试验,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。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之间的新型结构形式。试验结果与ANSYS模拟结果吻合较好,利用ANSYS软件进行仿真分析是测试结构动力特性的一种可靠方法。
In order to study the dynamic characteristics of silt hollow shear wall building of reinforced concrete, the modal test and pseudo-dynamic test of 1/3. 0 scale model of 6-storey building were made. Dynamic characteristic parameters such as periods, vibration modes, damping ratios, amplificatory coefficients of seismic action were obtained. On the basis of the experimental study, it uses finite element analysis software ANSYS to make modal analysis of the model structure. The results show that silt hollow shear wall building of reinforced concrete is a new type of structure which is between frame structure and traditional shear wall structure. The experimental results accord well with simulation results with ANSYS, which shows simulation with the software ANSYS is a reliable way to test structure＇s dynamic characteristics .
