附加柱是巨子型有控结构体系(Mega-Sub Controlled Structure System,即MSCSS)中的关键因素,为了确定MSCSS的细部构造,本文对附加柱的连接方式进行了研究。针对四种附加柱的构造方案,利用切球选点方法,确定了91个不同材料参数及地震强度的随机工况,在此基础上进行了随机巨子型有控结构体系在随机激励下的动力特性分析;基于概率密度演化理论,对各种附加柱构造情况下MSCSS的位移、加速度、附加柱应力的均值和标准差进行对比,确定了最佳的附加柱构造方案。结果表明,释放MSCSS附加柱顶端的水平约束,可以有效地降低MSCSS的加速度、位移、附加柱应力响应,使MSCSS抗震性能的优越性得到充分的发挥。本文提出的MSCSS基本构造形式可为MSCSS的进一步深入研究提供依据。
The additional column is a key factor in the Mega-Sub Controlled Structure System (MSCSS). In order to determine the detail structure of the MSCSS, the attachment method of the additional column is studied in this paper. According to the construction scheme of four kinds of additional columns, the stochastic working conditions of 91 different material parameters and seismic intensity are determined by using the method of cutting the ball point. On the basis of this, the stochastic excitation of the random giant controlled structure system Based on the theory of probability density evolution, the displacement and acceleration of MSCSS and the mean and standard deviation of additional column stress are compared, and the best additional column construction scheme is determined. The results show that releasing the horizontal constraint of MSCSS additional column can effectively reduce the acceleration, displacement and additional column stress response of MSCSS, so that the superiority of MSCSS seismic performance can be fully exerted. The basic structure of MSCSS proposed in this paper can provide a basis for further study of MSCSS.
