遗传演化结构优化算法自提出以来，研究主要针对单荷载工况的情形，研究成果对于指导实际工程设计存在缺陷。为了满足工程应用的需求，本文以 ANSYS有限元软件的非线性分析为平台，选用 solid65单元和link10单元分别模拟混凝土单元和钢筋单元，将分离式模型遗传演化结构优化推广到复杂应力构件多荷载工况下的配筋优化。通过选用开洞深梁和开洞剪力墙作为数值算例以验证，分离式模型遗传演化结构优化可以综合考虑多个荷载工况的影响，减少人为因素的干扰，直观地计算出钢筋配置方案，很好地完成复杂应力构件在多荷载工况下的配筋优化设计，所得的结果符合受力机理，且不会使钢筋过度集中，还因为提高了钢筋的利用效率，所以相比弹性应力设计方法节省了用钢量。

The genetic evolutionary structural optimization (GESO)is used for single loading case stud-y,but it still needs to be improved in practical engineering.In this paper,Separated elements model GESO was used to design reinforcement layout of the reinforced concrete (RC)members under complex elements stress states and multiple loading cases in order to fulfill the needs of engineering application.Separated el-ements model GESO involves the nonlinear analysis of ANSYS finite element software as a platform,in which solid65 element is chosen as the concrete element,while link10 element is regarded as the reinforce-ment element herein.Separated elements model GESO is further verified by considering deep beams and shear walls with openings as the numerical examples.The reinforcement layout of RC members under complex stress states can be optimized under multiple loading cases including loading combination.The in-fluence of subj ective factors has been dramatically reduced with intuitive reinforcement layout results, which are in accordance with the stress mechanism and will not lead to centralized reinforcement layout. The application of separated elements model GESO can save steel consumption by comparing with elastic stress design method,since the utilization efficiency of reinforcements is also improved.
