| 摘 要： | 提出了在高耸建筑物中设置纵向夹层控制结构地震响应的措施,并给出了分析方法。该方法将夹层隔开的各子结构假设为弯曲振动的梁,子结构间用分布弹簧—阻尼器连接,通过两次振型分解整个结构体系化为n个单自由度体系来分析。最后通过实例进行了参数研究和控制地震响应效果的分析。

| Abstract: | The response of high-rise buildings to an earthquake can be controlled by putting a visco-elastic layer between the two parts of the structure. Each part of the structure separated by the layer but connected to other part by a spring-damper is taken as a vibrating beam. The whole system is divided into n simple-degree-of-freedom systems through two times of vibration mode decomposition. The study on relevant parameters and the analysis of the control of seismic response are carried out through a numerical example. |
