| 摘 要： | 以文献「１」有关条文为约束条件，框架柱最轻为目标函数，柱截面惯性矩国设计变量，建立了剪切型多层钢框架抗震优化设计数学模型。采用Ｌａｎｃｚｏｓ方法求解特征值问题，求出自振周期和振型，并在ＩＢＭ－ＰＣ／ＸＴ微机上实现。实例表明，本文研制的优化程度收敛速度快，计算结果可靠。

| Abstract: | In this paper we constructed a mathematical model of the anti seismic optimal design for high rise steel frame structure of shear type. With the standard clauses in literature as the constraint conditions, the lightest weight of the frame posts as the objective function, and the section moments of inertia of the posts as the design variables, we use Lanczos method to solve the eigen problem. This is realized on an IBM PC/XT computer. An example shows that the convergence speed of the optimal programme suggested in this paper is fast and the computation results are reliable. |
