摘要: 襄陽(yáng)市圖書(shū)館高 32m,塔樓周邊布置有多個(gè)“知識(shí)樹(shù)”造型抽象而來(lái)的若干喇叭狀筒,屋面造型源自樹(shù)冠,懸挑跨度達(dá) 30m. 結(jié)構(gòu)在充分理解建筑創(chuàng)意的基礎(chǔ)上,將周邊各“知識(shí)樹(shù)”造型設(shè)計(jì)成變直徑鋼筋混凝土殼筒;屋面大懸挑則以簡(jiǎn)單的變截面實(shí)腹式鋼梁實(shí)現(xiàn),并在懸挑的根部設(shè)置斜撐,以減小懸挑梁的受力. 在實(shí)現(xiàn)建筑與結(jié)構(gòu)完美統(tǒng)一的同時(shí),最大限度地追求受力合理,分析結(jié)果表明,該結(jié)構(gòu)具有優(yōu)良的抗震性能,能夠滿(mǎn)足預(yù)期的性能目標(biāo).

Abstract: The height of Xiangyang Library is 32m. Around the tower, there are number of horn-shaped tubes thatabstracted from the “knowledge tree” shape. The roof shape is inspired by the tree crown, its cantilever span around 30m.On the basis of fully understanding the architectural creativity, the structural specialty designs the surrounding “knowledgetree” shapes into variable diameter reinforced concrete shell tubes, while the roof overhanging is realized by simple solidweb steel beams with variable cross-section, and diagonal braces are set at the root of the overhanging to reduce the stress ofthe cantilever beam. While realizing the perfect unity of the architecture and the structure, the maximum pursuit ofreasonable stress is achieved. The results show that the structure has excellent seismic performance and can meet theexpected performance objectives.

Keywords: Xiangyang Library; complicated connector; reinforced concrete shell tube with variable diameter;self-balancing; diagonal brace; performance design
