摘要:从虚功角度将基于层间位移约束的高层建筑规则结构多约束优化问题转化为基于顶层整体转动的单约束问题，并提出了基于虚功的单步优化法.通过算例分析了单步优化法应用情况，并将其优化结果与SAP2000有限元分析软件优化结果进行对比.结果表明：针对层间位移约束，采用单步优化法用钢量节省约10%.



Abstract:The multi-constrained optimization problem of regular high-rise structures based on inter-story displacement constraints was transformed into a single constraint problem. On this basis, the single-step optimization method（SOM） based on virtual work was proposed. The optimization results of SOM were compared with the optimization results of SAP2000. The results show that SOM based on virtual work can reduce the mass of material by 10%.
