摘　　要：±800 kV特高压换流站辅助控制楼主体结构高度较小,楼梯间突出屋面部分高度较大,地震作用下鞭梢效应明显。建立8种计算模型,对4种输入条件下模型的结构响应进行了探讨。研究表明:辅助控制楼结构计算主要控制指标为层间位移角。地震烈度为6度、加速度为0.05g、特征周期为0.45 s时,建议模型1,其性能指标可满足规范限值要求。地震烈度为7度、加速度为0.10g、特征周期为0.45 s时,建议模型2、模型3和模型5,结构响应可满足规范限值要求。地震烈度为7度,加速度为0.10g、特征周期为0.75 s及地震烈度为7度、加速度为0.15g、特征周期为0.45 s时,建议模型4和模型6,计算结果可满足规范限值要求;地震烈度为7度、加速度为0.15g、特征周期为0.75 s及地震烈度为8度、加速度为0.20g时,建议采用框架剪力墙结构。The height of the main structure of auxiliary control building of±800kV UHV converter station is small,and the height of partial roofing part is large.Whipping effect under earthquake is obvious.The 8 structural calculation models have been established to analyze the structural response of models under 4 input conditions.The research shows the main control index of the auxiliary control building structure calculation is interlayer displacement angle.When the seismic intensity is 6 degree,the acceleration is 0.05g,and the characteristic period is 0.45 s,the model1 is advised.When the seismic intensity is 7 degree,the acceleration is 0.10g,and the characteristic period is 0.45 s,the performance indicators of model 2、model 3 and model 5 can meet the specification limit requirements.When the seismic intensity is 7 degree,the acceleration is 0.10g,the characteristic period is 0.75 s and the seismic intensity is 7 degree,the acceleration is 0.15g,the characteristic period is 0.45s,model4 and model6 are advised.When the seismic intensity is 7 degree,the acceleration is 0.15g,the characteristic period is 0.75 s and the seismic intensity is 8 degree,the acceleration is 0.2g,the characteristic period is 0.45 s,the model 8 which is frame shear wall structure is advised.
