高层建筑结构分析的新方法

样条子域法是高层建筑结构分析的一种新方法。本文利用样条子域法对高层建筑结构进行了分析,建立了高层建筑结构的各种样条子域,导出了静力问题、动力问题、稳定性问题、几何非线性问题、塑性极限问题及结构与地基相互作用问题相应的计算格式。对这种方法,我们已用FORTRAN语言编制了程序。效果很好。实践证明,利用这种方法分析高层建筑结构是一种经济有效的方法,比有限元法及有限条法都优越。

NEW METHOD OF TALL BUILDING STRUCTURE ANALYSIS

Spline Subregion Method (SSM) is a new method of structural analysis on tall buidings. This paper is used by SSM to analyse structure of tall buildings and set up various SSM of tall tructures, and lead to calculation formulas of statics, dynamics, stabilities, geometrical non—linear, plasticultimate and interactions of structure, soil and foundations. The programme system is researched by SSM (Fortrain—4) and practices of calculations and engineerings proved very effective and economic. It is better than finite element and finite strip method.
