［摘要］張北可再生能源柔性直流閥廳采用鋼排架柱作為承重構(gòu)件，結(jié)構(gòu)抗側(cè)力構(gòu)件可選擇普通支撐或屈曲約束支撐。通過對(duì)防屈曲支撐方案、普通支撐方案1、普通支撐方案2在多遇及罕遇地震作用下的時(shí)程分析得出位移、塑性鉸分布等不同的結(jié)構(gòu)地震作用響應(yīng)結(jié)果。結(jié)果表明，防屈曲支撐在為結(jié)構(gòu)提供附加剛度、耗能減震的同時(shí)取得良好的經(jīng)濟(jì)效益； 同時(shí)根據(jù)電力系統(tǒng)的特殊功能性要求對(duì)國(guó)家重點(diǎn)工程張北項(xiàng)目的電氣設(shè)備和廠房結(jié)構(gòu)在地震下的基本性能目標(biāo)提出建議。

Abstract:The  Zhangbei Renewable Energy flexible DC valve hall  adopts steel bent column as the main load-bearing member. The lateral resistance member of the structures can choose ordinary braces or buckling-restrained braces. Through time history analysis of buckling-restrained braces, ordinary support plan 1 and ordinary support plan 2 under frequent and rare earthquakes, different structural seismic response results such as displacement and plastic hinge distribution were obtaine. The results show that the buckling-restrained braces provide additional rigidity and energy dissipation and seismic reduction for the structure while having achieved economic benefits. At the same time, according to the special functional requirements of the electrical power system, suggestions are proposed on the basic performance objectives of the national key project Zhangbei project for electrical equipment and plant structures under earthquakes.

Keywords:electric power system; buckling-restrained brace; ordinary brace; energy dissipation and seismic reduction
