本文在弹性范围内对空间剪力墙结构和具有双线性变形性质的层状横向各向同性地基,分别采用双重扩大子结构有限元分析和作者建立的弹性半空间的有限层分析,给出高层空间剪力墙结构与地基共同作用的通用分析方法和程序,使得在不增设外部设备的条件下利用32K内存量的计算机分析共同作用的三维问题成为可能。通过对上海一幢有代表性的高层建筑进行模拟计算和实测结果的综合分析,探讨了空间剪力墙结构与地基共同作用的机理、结构刚度的贡献以及箱基和上部结构应力的变化规律,初步考察了地基各向异性的影响。
In the elastic range, the spatial shear wall structure and the layered transversely isotropic foundation with bilinear deformation properties are respectively analyzed by the double-expanded substructure finite element analysis and the finite layer analysis of the elastic half-space established by the author. The common analysis methods and procedures for the interaction of the high-rise space shear wall structure and the foundation make it possible to analyze the combined three-dimensional problems using a computer with 32K memory without the addition of external equipment. Through a comprehensive analysis of a representative high-rise building in Shanghai and the results of actual measurement, the mechanism of joint action of space-shear wall and foundation, the contribution of structural stiffness, and the variation of stress in the box foundation and superstructure are discussed. The influence of the anisotropy of the foundation was initially examined.
