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。
In this paper, the combination of displacement iteration method and computer technology is used to study the accurate and simple calculation methods for high-rise frames, frame shears, and framed limb walls. In the analysis of internal forces, the influences of column axial deformation, shear deformation of shear walls, and the rigid region of the coupled limb shear wall on the internal forces and displacements of the structure are considered. Since the iterative formula is formed automatically according to the node number, the computer memory and time can be saved. Therefore, a high-level frame-shear structure can be analyzed with a microcomputer such as PC-1500. A number of examples have been calculated using the “ITAN-1” program prepared by the method in this paper. The results are satisfactory, indicating that this method has certain practicality.
