［摘要］北京汽車博物館為體型復(fù)雜的場(chǎng)館結(jié)構(gòu)，中廳周邊柱上下錯(cuò)位，采用型鋼混凝土轉(zhuǎn)換節(jié)點(diǎn)?；诜蔷€性有限元通用軟件，采用纖維梁和分層殼單元，對(duì)其整體結(jié)構(gòu)進(jìn)行了彈塑性靜力推覆和動(dòng)力時(shí)程分析。采用精細(xì)模型對(duì)復(fù)雜節(jié)點(diǎn)進(jìn)行彈塑性分析，得到了節(jié)點(diǎn)的承載力N-M相關(guān)曲線，并據(jù)此驗(yàn)證了轉(zhuǎn)換節(jié)點(diǎn)的可靠性。分析結(jié)果表明，結(jié)構(gòu)在小震及設(shè)防烈度地震作用下基本處于彈性狀態(tài)，在罕遇地震作用下主結(jié)構(gòu)能夠保持較好的工作狀態(tài)。

Abstract:The structure system of Beijing Automobile Museum is irregular and complicate. The columns surrounding the center hall are stagger between stories, and the steel reinforced concrete composite transferring system is used to strengthen the joints. Based on nonlinear finite element software, using fiber beam element and layered shell element, push-over analysis and elastic\|plastic time-history analysis are carried out. Based on refined finite element model, elastic\|plastic analysis is made to study the load-bearing capacity of complicate joints, N-M interaction curves are obtained and the reliability of joints is proved. The results show that the structure is elastic under frequent earthquake and inter-mediate earthquake and the main structure has good performance under rare earthquake.

Keywords:automobile museum; seismic performance; elastic\|plastic; load-bearing capability of joint; N-M interaction curves
