金港文化中心长悬挑结构专项设计
|
摘要
金港文化中心是典型的钢筋混凝土大悬挑结构。对长悬挑结构设计中的常见问题和解决办法进行了总结,并在概念设计、初步设计和施工图设计的不同阶段,始终贯穿了"减挑、减荷、增抗力"的原则,提出了优化竖向构件位置、梁布置方向、梁宽及梁间距比选、减小绿化荷载、增加预应力设计、加强钢筋锚固构造、重视结构防倾覆设计等多种手段,使设计成果满足了结构承载力、变形的需要,尽量做到了材料节省,并实现了预期的建筑效果。
Large span cantilever design is the main issue in the structure design of Jin Gang Cultural Center. The challenges and solutions of long span cantilever design were summarized. In the process of conceptual design, preliminary design and construction drawing design, the principle of "reducing span and load and increasing the resistance capacity" ran throughout, and the aspects such as layout of walls and columns, beam direction, beam width, beam spacing, reducing soil load, pre-stressed concrete design, steel rebar anchorage and increasing structural overturn resistance capacity were discussed, by which the load bearing capacity, deformation, economic and architectural needs are satisfied at the end.
