本文针对高层筒体结构在静力荷载作用下的内力和位移分析提出了最小二乘子域配点解法。把框筒分成若干个子域,每个子域折算为连续体,分析其受力性能并进行整体分析以建立数学模式,然后对其控制方程、子域交界条件等配点得到一组配点方程而易于求解。文中建议了满足位移边界条件的位移试函数,给出了框简结构算例,同时也给出了筒申简结构的处理办法。本文方法来知量甚少,全部计算可在微机甚至袖珍机上进行。
In this paper, the least squares sub-region collocation method is proposed for the internal force and displacement analysis of high-rise tube structures under static load. The box is divided into several sub-domains. Each sub-domain is converted into a continuum, and its force performance is analyzed and the whole analysis is performed to establish a mathematical model. Then a set of collocation equations are obtained for its collocations such as the control equations and the subfield boundary conditions, and it is easy to solve. . In this paper, we propose a displacement trial function that satisfies the displacement boundary conditions, gives an example of the simplified structure of the box, and also gives the solution to the structure of the tube reduction structure. This method has very little knowledge, and all calculations can be performed on a microcomputer or even a pocket machine.
