摘要: 襄阳市图书馆高 32m,塔楼周边布置有多个“知识树”造型抽象而来的若干喇叭状筒,屋面造型源自树冠,悬挑跨度达 30m. 结构在充分理解建筑创意的基础上,将周边各“知识树”造型设计成变直径钢筋混凝土壳筒;屋面大悬挑则以简单的变截面实腹式钢梁实现,并在悬挑的根部设置斜撑,以减小悬挑梁的受力. 在实现建筑与结构完美统一的同时,最大限度地追求受力合理,分析结果表明,该结构具有优良的抗震性能,能够满足预期的性能目标.

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
