摘要
介绍了金湾航空城市民艺术中心的单层钢网格屋盖结构设计理念和结构体系。在解构造型屋盖的空间组成与分析其几何特征的基础上,确定造型屋盖采用单层钢网格结构形式,并通过树形柱、摇摆柱和屋面支撑支承于主体结构之上,从而达到建筑结构完美融合与结构受力更合理的目的。整个单层钢网格屋盖结构被设计为由两级结构层次组成,形成传力明确的受力机制。对单层钢网格屋盖结构进行非地震和地震组合作用下的受力和变形分析、整体稳定性分析、关键节点分析,验证了本项目单层钢网格屋盖结构具有足够的刚度和承载力,并能达到预设的抗震性能目标,使轻薄单层钢网格屋盖跨越大空间的目标得以实现。同时,亦为这类造型复杂且建筑要求高的结构方案提供一种基于解构建筑空间形态的设计思路。
The design concept and structural system of single-layer steel grid roof of Jinwan Aviation City Civic Art Center were introduced.On the basis of analyzing the spatial composition and geometric characteristics of the modeling roof,it was determined that a single-layer steel grid structure was adopted for the modeling roof.The roof was supported by tree-like columns,rocker columns and roof bracing systems connected to the main structure,achieving a perfect integration of architecture and structure as well as more rational force distribution.The entire single-layer steel grid roof structure was designed with a two-level hierarchical system,forming a clear load-transfer mechanism.Structural analyses were conducted on the single-layer steel grid roof structure under non-seismic and seismic combined actions including force and deformation analysis,overall stability analysis and key joint analysis.The analysis results show that the single-layer steel grid roof structure of this project has sufficient stiffness and bearing capacity.And the anticipative seismic performance targets are achieved.The goal of a lightweight single-layer steel grid roof spanning large space has been achieved.At the same time,it also provides a design approach based on the deconstruction of architectural spatial form for structural schemes with complex geometries and high architectural requirements.
