（北京首鋼設(shè)計院  100043）
【提要】  某鋼鐵廠煉鐵系統(tǒng)中噴煤主廠房的二期工程受現(xiàn)場條件及工藝布置要求的限制，結(jié)構(gòu)平、立面布置及各層平臺的設(shè)備荷載分布均存在較大的不規(guī)則性。基于不同方案的對比分析，采用中心支撐鋼框架結(jié)構(gòu)方案。用Pushover分析方法對擬定方案在罕遇地震作用下的抗震性能進行了補充驗算，校核了方案的合理程度，并針對薄弱部位采取了相應(yīng)的加強措施。
【關(guān)鍵詞】  中心支撐鋼框架結(jié)構(gòu)  不規(guī)則性  方案優(yōu)化  推覆分析  合理性

Abstract:Considering field condition and processing setup，irregularity of the secondstage PCIsystem main structure and load distribution of equipments are severe. The project is determined based on the comparison of different models. Pushover analysis of the model is performed，the reasonability is validated and reinforced construction measures are taken for weak position of the structure.
Keywords:steel braced frame structure；irregularity；project optimize；Pushover analysis；reasonability
