摘　　要：针对阀厅结构在纵向地震作用下存在较明显的扭转效应,对阀厅结构进行结构优化设计,并对比分析在多遇地震作用下原结构模型与优化结构模型的地震响应。分析表明,采用轻质混凝土砌块砖减小结构自重,适当地加大剪力墙、构造柱和圈梁截面尺寸均可以改善阀厅结构纵向扭转效应,其中采用轻质混凝土砌块砖的方式控制结构纵向扭转效应最明显;适当增大构造柱和圈梁截面能有效地控制结构横向地震响应;结构抗侧力构件的参数变化对悬吊设备地震响应的影响不显著。Due to significant torsion effect of the valve-hall structure under longitudinal earthquake actions, structural optimization designing was carried out, and seismic responses of the original structure model and optimized structural model under conventional earthquake actions were compared. Results show that the longitudinal torsion effects of the valve hall structure can be decreased by adopting ｜ightweight concrete bricks, appropriately increasing the cross-sections of the shear walls, constructional columns and ring beams, among which application of lightweight concrete bricks is the most effective way. Suitable enlargement of the cross-sections of constructional columns and ring beams can effectively control horizontal seismic response of the valve hall structure. The influences of the parameters of the structural lateral resist components changing on the seismic responses of the suspended equipments are not significant.
