馮知夏 孫澄潮 (泛華建設(shè)集團泛華工程有限公司 北京 100088)申 林 (中國建筑標準設(shè)計研究院 北京 100044)[提要] 北京展覽館綜合樓展示中心采用了框架剪力墻-空間鋼桁架結(jié)構(gòu)體系，對這種新型的空間結(jié)構(gòu)形式采
用了不同程序進行對比分析計算。分別采用了剛性和彈性樓板假定，并考慮了垂直地震作用、溫度應(yīng)力對結(jié)構(gòu)內(nèi)力與變形的影響，驗算了罕遇地震作用下結(jié)構(gòu)的彈塑性變形。對影響結(jié)構(gòu)抗震性能的關(guān)鍵節(jié)點進行了抗震設(shè)計，為混合結(jié)構(gòu)在高烈度區(qū)的應(yīng)用積累了經(jīng)驗。

Abstract: Frame shear wall-space steel truss structure system is adopted in Beijing exhibition center building. Different procedures are adopted to calculate and analyze the new style space structure.The influences of rigid and elastic floor slab assumtion, vertical earthquake action and the temperature stress on the structural internal force and deformation are analyzed. The structural elastic-plastic deformation under infrequent earthquake is checked. The details of seismic design for key joints that affect structure seismic capability are carried out. The designuorks accumulate experience for the applications of hybrid structure at high intensity regions.
Keywords: steel-reinforced concrete mixted structure; frame shear wall-space steel truss; seismic design; rigid or elastic slab assumtion; temperature stress; joint construction
