A simplified method for earthquake actions on suspended equipments in valve-hall structures

针对带悬吊阀换流站阀厅结构悬吊设备设计方法上存在的欠缺,本文对悬吊设备的设计方法进行了分析研究。根据地震作用下带悬吊阀阀厅结构的非线性动力时程分析结果以及悬吊设备的特性,建立了地震作用下悬吊设备的计算模型,提出简化计算方法,并将该简化计算方法与其他计算方法分析所得结果进行对比分析,验证了该计算方法可行合理,可为带悬吊阀阀厅结构体系的抗震设计提供相应的计算依据。

The suspension design was analyzed because of the deficiency in the current design method for suspended valves in valve-hall structures. Based on the nonlinear dynamic time history analysis results under earthquake actions and the characteristics of the suspension equipment, the calculation model of suspension equipment under the earthquake effect was established and the simplified calculation method was proposed. The comparison between the simplified calculation method and other methods was carried out. Results show that the method is feasible and reasonable, and provide a basis for seismic design of the valve-hall structure with suspended valves.
