The lately proposed mega sub-controlled structure (MSCSS) remarkably improved the seismic resistance ability and reduced vibration effects much more than the mega substructure (MSS). However, the controlling effectiveness and its optimization remain a significant concern. In this paper, a new configuration of MSCSS is analyzed in which viscous dampers are optimally arranged between mega-frame and substructural frame and optimal damper parameters are investigated. Also, rubber bearings are designed and introduced at the top of the additional column to ease the horizontal constraints between the additional column and mega-floor beam and improve the structural design of MSCSS, so that the structure has a larger span and further reduces the structural response. The result showed that optimal parameters of the damper and its optimal arrangement have a significant influence in the control effectiveness of MSCSS. Furthermore, the addition of a rubber bearing at the top of the additional column improves the mechanical behavior of the column and further reduces the acceleration response of both the mega-frame structure and the substructure. This paper also shows that the percentage reduction of the acceleration is more within the substructure than at the mega-frame structure. The seismic response of this structure under El Centro is less than the Taft (NE) wave and the percentage reduction is more under the Taft wave than under the El Centro wave.

地震作用下巨型次控结构系统（MSCSS）的设计、优化及非线性响应控制分析

最近提出的巨型子结构（MSCSS）比巨型子结构（MSS）显着提高了抗震能力并减少了振动效应。然而，控制效果及其优化仍然是一个重要的问题。在本文中，分析了一种新的MSCSS配置，其中粘性阻尼器在巨型框架和子结构框架之间优化布置，并研究了最佳阻尼器参数。同时，在附加柱顶部设计并引入橡胶支座，以缓解附加柱与巨型楼板梁之间的水平约束，改进MSCSS的结构设计，使结构具有更大的跨度，进一步减少结构回复。结果表明，阻尼器的最优参数及其最优布置对MSCSS的控制效果有显着影响。此外，在附加柱顶部增加橡胶支座，改善了柱的力学性能，进一步降低了巨型框架结构和下部结构的加速度响应。本文还表明，与巨型框架结构相比，下部结构内的加速度降低百分比更多。该结构在 El Centro 波下的地震响应小于 Taft (NE) 波，并且在 Taft 波下比在 El Centro 波下的衰减百分比更大。在附加柱的顶部增加了一个橡胶轴承，改善了柱的机械性能，并进一步降低了巨型框架结构和下部结构的加速度响应。本文还表明，与巨型框架结构相比，下部结构内的加速度降低百分比更多。该结构在 El Centro 波下的地震响应小于 Taft (NE) 波，并且在 Taft 波下比在 El Centro 波下的衰减百分比更大。在附加柱的顶部增加了一个橡胶轴承，改善了柱的机械性能，并进一步降低了巨型框架结构和下部结构的加速度响应。本文还表明，与巨型框架结构相比，下部结构内的加速度降低百分比更多。该结构在 El Centro 波下的地震响应小于 Taft (NE) 波，并且在 Taft 波下比在 El Centro 波下的衰减百分比更大。
