摘要
研究高烈度设防地区高端阀厅结构的动力特性,对全钢、混合阀厅两种完全不同结构进行抗震分析,通过反应谱及时程分析获得两种结构型式有阀、无阀模型的抗震性能。分析阀厅结构模态、结构规则性、底部反力、阀塔位移、阀塔加速度、阀塔吊杆应力,多方面对阀厅结构进行评价,全钢结构阀厅抗震性能优于混合结构。对于高地震烈度换流站高端阀厅,推荐采用全钢结构。
In this paper,the dynamic characteristics of the high-voltage valve hall structure in the high seismic intensity area are studied.The seismic analysis of the two completely different structures,full steel and mixed structure,is carried out.The seismic performance of the valve and valveless models is obtained through response spectrum and time-history analysis.The structural modal,structural regularity,bottom reaction force,displacement of valve tower,acceleration of valve tower,and stress of valve tower rod are analyzed.The evaluation of valve hall structure in many aspects shows that the seismic performance of full steel structure is better than that of mixed one.In the high seismic intensity area,the high-voltage valve hall is recommended to adopt full steel structure.
