摘　　要：针对某工程空冷混合支架结构体系,建立有限元模型,先对比分析冷凝器作为结构一部分和作为设备荷载两种极端情况下结构的抗震性能,然后再分析冷凝器特性参数变化时空冷支架结构体系的动力特性和抗震性能.结合以往的研究成果确定冷凝器的特性参数在何种情况下与真实的结构特性更吻合,最终确定冷凝器特性参数.为空冷支架结构设计特别是A型架的结构设计提供参考依据.In view of an air cooled condenser hybrid platform structure,firstly,after establishing the finite element model by using SAP2000,the results of modal analysis and the aseismic performance analysis are compared in two situations that the condenser as a part of structure and as the equipment load.Then the aseismic performances of air cooled condenser platform under different properties of condenser,are analyzed.In contrast to the formerly research results,that in which kind of situation the structure is closer to the real structural dynamic property,is determined.Finally,the condenser characteristic parameters are determined.And the condenser's characteristic parameters can be used in the platform structure design,especially in the A-shaped support structure design.
