多高层建筑钢结构实用优化方法研究

根据文献中位移准则优化算法。针对多高层建筑钢结构特点，给出了基于造价最低目标的风荷栽及地震作用下建筑钢结构位移准则优化算法公式；并提出了整体约束（层间位移限制）和局部约束（强度、稳定与挠度限制）相结合的实用综合优化算法策略；此算法不仅适用于多层钢框架结构，而且对于高层钢结构也有很好的收敛性，且在优化结果的同时满足了整体与局部约束，具有很好的直接实用性。

Practical Optimization Method for Structural Design of Multi and Tall Steel Buildings

Based on the existed fruits in the displacement rule design, and aiming at optimization of muhi and tall steel buildings, the paper achieves innovative developments in disposing earthquake load and combining with local optimization methods. The results of case analysis show that the new method has good optimization convergence and practicality.
