| 摘 要： | 指出偏心支撑结构的不足,提出了在偏心支撑结构的支撑上设置粘弹性阻尼器(称之为消能偏心支撑)来弥补其不足,分析了消能偏心支撑结构的消能减震原理和单自由度下的地震响应,接着以实例对比了偏心支撑结构与消能偏心支撑结构的位移、内力等。分析结果表明:消能偏心支撑具有良好的抗震性能,起到了"双保险"的作用。

| Abstract: | Pointing out the disadvantages of the eccentrically braced frames,this paper puts forward viscoelastic dampers connected with braces in eccentrically braced frames(which are referred to as energy dissipation eccentrically braced frames) so as to make up the shortage of the eccentrically braced frames.The principle of energy dissipation and earthquake-response of SDOF of the energy dissipation eccentrically braced frames are analyzed.It is compared the internal force,displacement and relative displacement of eccentrically braced frames and energy dissipation eccentrically braced frames through an example.The analysis result proved the energy dissipation eccentrically braced frames have the better earthquake resistant behavior and function of "double fuses". |
