某高层钢桁架与钢拉索组合悬挂体系结构设计
Structural Design of a High-Rise Suspension System with Combination of Steel Truss and Steel Cable
为满足建筑使用要求,某办公塔楼采用了钢桁架与钢拉索组合悬挂体系。对典型的高层悬挂体系整体结构进行了小震弹性分析、中大震等效弹性分析、大震弹塑性分析,并进行了钢拉索承载力分析、楼板舒适度分析、关键节点受力分析等专项分析,分析结果表明,核心筒悬挂结构悬挑转换体系具有较高的安全储备,经合理设计可以作为高层建筑的一种结构形式应用于实际工程。此外,针对悬挑转换结构的特点,提出了可行的施工方案。
To meet the architectural requirements, an office tower has adopted an integrated suspended structural system with combination of steel trusses and steel cables. This article conducted small earthquake elastic analysis, medium to large earthquake equivalent elastic analysis, and large earthquake elastoplastic analysis on the overall structure of a typical high-rise suspension system. Specialized analyses such as steel cable bearing capacity analysis, floor comfort analysis, and stress analysis of critical joints stress are also conducted. The analysis results show that the core tube suspension structure system has a high safety reserve and can be used as a structural form of high-rise buildings in practical engineering after reasonable design. In addition, feasible construction plans have been proposed based on the characteristics of cantilever conversion structures.
