[摘要] 研究通过优化平台HyperStudy调用结构分析软件SAP2000进行结构抗震优化设计。利用SAP2000的API功能开发了OptiDesign程序，OptiDesign可以调用SAP2000进行求解并将SAP2000的计算文本结果输出及反馈到HyperStudy，从而实现了优化流程的自动控制，提高了结构优化效率。以结构楼层位移角、位移比和竖向构件轴压比等作为优化约束条件，以构件截面尺寸为优化变量，以结构总重量最小为目标对某框架结构进行优化。算例结果表明，本文方法可作为建筑结构优化的一种新手段。

Abstract: Seismic structural design optimization was performed by HyperStudy calling structure analysis software SAP2000. The program OptiDesign was developed base on the function of SAP2000 API, it can call SAP2000 solving and feedback text results of SAP2000 to HyperStudy. The optimal process was controlled automatically and the efficiency of structural optinuzation was improved. The total mass of a frame structure was optimized under the optimal constraints of drifts, displacement ratio, axial compression ratio and optimal variables of member section size. The optimal example shows that this method can be used as a new means in building structural optimization.
