本文提出了分析常用高层建筑结构的样条子结构法。计算时,结构被划分成几种典型的子结构:框筒子结构、剪力墙子结构、核芯筒子结构、框架——剪力墙子结构和离散柱子结构,子结构的位移场是用样条函数与三角级数的乘积来描述的,在变分原理的基础上形成子结构的刚阵,考虑各子结构间的位移协调与边界条件。从而建立了结构总体刚度矩阵。与通常的有限元及有限条法相比,具有精度高,计算量小,程序易编制等特点,且对所有的高层建筑结构可以统一处理,应用甚为简便。通过实例计算,这个方法能满足工程设计的要求
This paper proposes a spline substructure method for analyzing high-rise building structures. When calculating, the structure is divided into several typical sub-structures: box-tube sub-structure, shear wall sub-structure, core barrel sub-structure, frame-shear wall sub-structure and discrete column sub-structure, the sub-structure displacement field is used The product of the bar function and the triangular series is described. Based on the variational principle, a sub-structured rigid matrix is formed, and the displacement coordination and boundary conditions between the sub-structures are considered. Thus, the overall stiffness matrix of the structure is established. Compared with the ordinary finite element method and the finite strip method, it has the characteristics of high precision, small amount of calculation, and easy programming. It can handle all high-rise building structures in a unified manner and is easy to apply. By example calculation, this method can meet the requirements of engineering design
