［摘要］嘉德藝術(shù)中心采用鋼板混凝土核心筒-鋼框架結(jié)構(gòu)體系。由于建筑空間要求，大部分框架柱不能貫通，四個(gè)核心筒為主要的傳遞豎向荷載和抗側(cè)力構(gòu)件。5～8層平面外擴(kuò)，通過(guò)大跨度懸挑桁架支承，平面四周設(shè)置大跨度空腹桁架。通過(guò)對(duì)結(jié)構(gòu)進(jìn)行整體計(jì)算分析，保證了主體結(jié)構(gòu)特別是鋼板混凝土核心筒滿(mǎn)足相應(yīng)的抗震性能目標(biāo)。介紹了鋼板混凝土組合剪力墻的計(jì)算方法、應(yīng)用經(jīng)驗(yàn)，以及懸挑桁架在豎向地震作用下的響應(yīng)的計(jì)算方法和防倒塌設(shè)計(jì)。比較了在大跨、大懸挑區(qū)域設(shè)置質(zhì)量調(diào)諧消能器（TMD）前后樓板的豎向振動(dòng)響應(yīng)，結(jié)果表明在舒適度設(shè)計(jì)中，TMD的設(shè)置具有明顯的減震效果。［關(guān)鍵詞］嘉德藝術(shù)中心; 復(fù)雜結(jié)構(gòu)體系; 大跨轉(zhuǎn)換結(jié)構(gòu); 大跨懸挑桁架; 舒適度中圖分類(lèi)號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)18-0047-07
Structural design of Guardian Art CenterGao Ang, Zhen Wei, Sheng Ping(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: Guardian Art Center adopts composite steel plate concrete corewall-steel frame structural system. In order to satisfy the requirement of architectural space, most of frame columns can not be through to the foundation and four corewall structures are the main structure to transfer vertical loads and resist lateral forces. Due to the plan expanding outwards in 5 to 8 floors, the floors are supported with large-span cantilever trusses and large-span vierendeel trusses around the plane. Through the analysis of the whole structure, seismic performance targets of the main structure, especially the steel plate concrete corewall, were ensured to meet the corresponding seismic behavior goals. The calculation method and application experience of steel plate concrete composite shear wall were introduced as well as the calculation method and progressive design of the cantilever trusses under vertical seismic actions. The vertical vibration responses of the TMD in the large-span and large-cantilever area were compared, which indicates that the setting of the TMD has a significant effect on the energy dissipation in design of comfort degree.Keywords: Guardian Art Center; complex structural system; large-span transfer structure; large-span cantilever truss; comfort degree
