| 摘 要： | 运用小生境技术的改进遗传算法对半刚接多层钢框架进行优化设计,提高了算法的收敛性,可直接从H型钢表或热轧型钢表中选取截面,并且从用钢量角度分析了二阶效应对半刚接钢框架的影响.实际算例表明半刚性连接会使二阶效应的影响增大,用钢量也随之增加. |
| 关 键 词： | 遗传算法 半刚接 非线性 钢框架 |

| Abstract: | A niche genetic algorithm based optimum design method is presented for nonlinear multistory steel frames with semi-rigid connections.The convergence rate is enhanced.Sections can be selected from H steel tables and the second-order effect is considered from the weights of steel.The result shows that the semi-rigid connections can make the second-order effect increase and the weights of steel also increase. |
| Keywords: | genetic algorithm semi-rigid connection nonlinear steel frame |
