［摘要］商丘文化藝術(shù)中心主要功能為劇場(chǎng)，除設(shè)有入口大廳、觀眾廳、主舞臺(tái)外，還在觀眾廳大跨度樓蓋頂上設(shè)置球幕影院，球幕影院球形頂（內(nèi)球）外設(shè)有懸掛步道的外球。各功能空間層疊交錯(cuò)，空間關(guān)系復(fù)雜，如何使豎向荷載、水平荷載傳力路徑明確、簡潔是本項(xiàng)目設(shè)計(jì)的難點(diǎn)及關(guān)鍵點(diǎn)。采用整體-局部-整體的設(shè)計(jì)思路，整體構(gòu)件布置后，先針對(duì)各個(gè)空間獨(dú)立設(shè)計(jì)，再進(jìn)行整體分析。入口大廳采用單排搖擺柱和交叉圓鋼管屋面桁架體系，單層搖擺柱僅承擔(dān)豎向荷載，水平荷載由周邊剪力墻及12m標(biāo)高混凝土平臺(tái)承擔(dān)；觀眾廳和主舞臺(tái)在施工階段釋放平面交叉鋼桁架體系的水平約束；內(nèi)球和外球采用單層網(wǎng)殼結(jié)構(gòu)體系，被主舞臺(tái)、觀眾廳外側(cè)柱、樓梯間剪力墻、12m標(biāo)高混凝土平臺(tái)等切割為不完整球殼。合理布置剪力墻，將各功能空間聯(lián)系到一起進(jìn)行整體分析。

Abstract:The main function of Shangqiu Culture and Art Center is theatre. Apart from the entrance hall, auditorium and main stage, a ball-curtain cinema is set up on the roof of the large-span floor of the auditorium. An outer ball with hanging walkway is set outside the ball roof of the ball-curtain cinema. The space of each function region is overlapping and complicated. It was the difficulty and key point of this project design to make the clear and concise transmission paths of vertical load and horizontal load. The whole-part-whole design idea was adopted. After the whole components were laid out, each space was designed independently and then overall analysis was conducted. The entrance hall adopts single row swing column and cross-section steel pipe roof truss system, where single-layer swing column only bears vertical load and horizontal load is borne by surrounding shear wall and concrete platform at 12m elevation; horizontal cross-section steel truss system is adopted in auditorium and main stage to release horizontal constraint in construction stage; inner ball and outer ball adopt the structural system of single-layer reticulated shell structure, which is cut into incomplete spherical shells by main stage, outer column of auditorium, stairwell shear wall, concrete platform at 12m elevation, etc. Shear walls were reasonably arranged to link each functional space to an overall part for analysis.

Keywords:embedded end; performance-based seismic design; horizontal stiffness; plane cross truss; reticulated shell with irregular boundary; concrete hollow truss; shear wall layout
