［摘要］襄陽行政中心主樓共12層，結(jié)構(gòu)高度48.1m，采用框架-剪力墻結(jié)構(gòu)體系。結(jié)合建筑立面形態(tài)和平面布局，外圍兩排框架采用了斜框架結(jié)構(gòu)，其中中庭開洞周邊為單跨框架。介紹了斜框架結(jié)構(gòu)的設(shè)計(jì)重點(diǎn)和對整體結(jié)構(gòu)的影響，基于抗震性能化設(shè)計(jì)方法，進(jìn)行了多遇地震作用下的彈性分析、設(shè)防烈度地震作用下關(guān)鍵構(gòu)件的性能分析和罕遇地震下的彈塑性分析。由于結(jié)構(gòu)超長，設(shè)計(jì)時考慮了溫度效應(yīng)的影響。分析結(jié)果表明，結(jié)構(gòu)能夠達(dá)到預(yù)期的設(shè)計(jì)目標(biāo)。

Abstract: The main building of Xiangyang Administration Center is a 12-story building above ground with the height of 48.1m. The reinforced concrete frame and shear wall is adopted in the building. According to the facade shape and plane layout of the building, the two rows of declining frame around the outside building are used. Some single-span frames exist around the open atrium. The influence of the declining frame on the whole structure, and the performance-based seismic design of the key members and the declining frame were introduced. Based on the method of performance-base seismic design, the elastic analysis under frequent earthquake, performance analysis of key members under intermediate earthquake and elastic-plastic analysis under rare earthquake were carried out. Because of the overlong structure, temperature action was considered during structure design. The analysis results show that the structure can meet the design goals.
Keywords: declining frame-shear wall; single-span frame; performance-based seismic design; temperature effect
