基于随机振动分析方法对大调谐质量比减振结构及普通巨型框架结构中巨梁层竖向地震响应问题进行探讨,并从实际构造的角度为解决大跨度巨梁层竖向动力响应过大问题提供设计建议。研究结果表明:巨梁层上最大竖向地震响应分布于中段附近;巨梁层于建筑上的位置越高,其竖向地震响应越大;相比其他巨梁层,大跨度巨梁层竖向地震响应同比增大;在大跨度巨梁层上设置子框架可对该巨梁层竖向地震响应起到抑制作用。
Based on the method of stochastic vibration analysis, the vertical seismic response of the large tuned mass ratio vibration-damping structure and the common giant-frame structure is discussed. In order to solve the problem of vertical dynamic response of the large-span beam, Provide design advice. The results show that the maximum vertical seismic response on the girder is distributed around the middle section. The higher the position of the girder on the building, the greater the vertical seismic response. Compared with other girders, The earthquake response increases year-on-year. Setting the sub-frame on the long-span girder layer can restrain the vertical seismic response of the girder layer.
