用微型计算机分析高层框架及框-剪结构体系的位移迭代法

本文用位移迭代法与电算技术相结合的方式,研究出高层框架、框剪、框架联肢墙等结构的精确而又简便的计算方法。在内力分析中考虑了柱的轴变效应,剪力墙的剪切变形,联肢剪力墙横梁刚域等对结构内力及位移的影响。由于按照结点编号自动形成迭代公式,可节省计算机内存及时间。因此用微机如PC-1500即能够分析高层框-剪结构。应用本文中的方法编制的程序“ITAN-1”计算了几个数例,结果令人满意,说明本文方法具有一定的实用性。

Analysis of Frame-Shear Wall Structure System with Displacement Iterative Method by Use of Pocket Computer

This paper presents an accurate and simple method for calculating internal forces and displacements of high-rise buildings by displacement iterative method and computer techniques.In the analysis of internal forces, the axial deformation of columns, shear deformation of shear walls as well as the effect of beam rigid area in coupled shear walls have been taken into account.For the purpose of saving time and computer storage, the iterative fomuias are automatically formed according to the numbering of nodes. The frame-shear wall structure can therefore be analyzed by pocket computer such as PC-1500.Some numerical examples are given using program "ITAN- 1" based on the method presented in the paper. The results obtained are quite satisfactory. It shows that the proposed method is simple and efficient.
