摘要:
分析了竖向地震作用下巨-子型控制结构体系MSCSS(Mega-sub eontrolled structural system)的反应机理,提出了带附加柱的MSCSS.采用串并联质点系计算模型,对带附加柱与不带附加柱MSCSS进行了时程对比分析,计算结果表明:带附加柱与不带附加柱MSCSS相比,带附加柱MSCSS不仅可以在结构上解决巨型梁的大跨度问题,而且在竖向地震下具有较好的控制效果.基于随机振动复模态理论,采用非平稳地震动模型,进一步探讨了带附加柱MSCSS的子结构层数和巨(型)梁刚度等参数对结构反应的影响,研究表明子结构层数和巨(型)梁刚度等参数对带附加柱MSCSS巨型梁的位移和加速度响应的影响均十分显著.
Abstract:
The reaction mechanism of the mega-subtype control structure system MSCSS (Mega-sub eontrolled structural system) under the action of vertical earthquake was analyzed, and MSCSS with additional columns was proposed. MSCSS with additional columns can not only solve the problem of large span of giant beams in structure, but also have good control effect under vertical earthquakes. Based on the stochastic vibration complex mode theory, the influence of the number of layers and the stiffness of the giant beam of the substructure with additional columns is further discussed by using the non-stationary ground motion model, and the results show that the influence of the number of layers of the substructure and the stiffness of the giant beam on the displacement and acceleration response of the MSCSS giant beam with additional columns is very significant.
