某树形建筑超限结构设计

Out-of-code structural design of a tree-shaped building

介绍了某树形建筑的结构设计思路、结构布置、传力路径、结构设计特点和关键节点设计,采用PMSAP和ETABS软件进行了悬挑结构人行舒适度分析和性能化设计。讨论了树形建筑的结构性能及不同施工顺序下结构显著不同的受力结果,并介绍了相应的基础设计。结果表明,树形建筑能够实现抗震延性目标,并能提供足够的抗震承载力,可以保障结构安全。

The design thought,structure layout,load transfer path,structural design characteristics and key nodes design of a tree-shaped building were introduced. PMSAP and ETABS software were used for pedestrian comfort analysis and performance design of the cantilever structure. The structural performance of the tree-shaped building and the different mechanical results of the structure under different construction sequences were discussed,and the corresponding foundation design was introduced. The results show that the tree-shaped building can realize the seismic ductility target,and can provide enough seismic bearing capacity,so that the structure is safe.
