【摘要】：廣州美術(shù)館建筑造型為水中盛放的英雄花,采用鋼管混凝土框架+鋼筋混凝土框架-鋼筋混凝土核心筒組合結(jié)構(gòu)體系。通過方案對比,合理地選擇4個核心筒的剪力墻布置,既保證其作為主要抗側(cè)力構(gòu)件的作用,又避免其剛度過大而導(dǎo)致地震作用下受拉嚴(yán)重的問題。為節(jié)省投資,根據(jù)建筑造型與結(jié)構(gòu)柱網(wǎng)分布,分區(qū)域地采用了鋼筋混凝土梁板和鋼梁-壓型鋼板組合樓板兩種樓蓋體系,同時針對大跨度鋼梁也采用了先鉸接后剛接的構(gòu)造措施,讓鋼梁支座與跨中均能充分發(fā)揮其受力性能。由于建筑層高限制,5層以上的辦公區(qū)域采用局部設(shè)置斜腹桿的跨層空腹鋼桁架結(jié)構(gòu)。為配合建筑造型和使用功能,采用了新型的變截面鋼管混凝土柱和梁柱節(jié)點(diǎn)。
[Abstract]:The architectural style of Guangzhou Art Museum is a heroic flower in water. The composite structure system of steel tube concrete frame reinforced concrete frame and reinforced concrete core tube is adopted. Through the comparison of the schemes, the reasonable selection of the shear wall arrangement of the four core tubes can not only guarantee its function as the main anti-lateral force member, but also avoid the serious problem of the tensile force caused by the earthquake due to its large stiffness. In order to save investment, two kinds of floor system, reinforced concrete beam-slab and steel-beam-profiled steel plate composite floor system, are adopted according to the architectural modeling and the distribution of structural column net. At the same time, the long span steel beam is constructed by hinge first and then rigidly, so that both the support and the middle span can give full play to their mechanical properties. Because of the height limitation of the building, the office area above 5 stories adopts the cross-storey steel truss structure with inclined web bar. In order to fit in with the building modeling and using function, a new type of concrete filled steel tubular column with variable section and Liang Zhu joint is adopted.
