摘要
以强外框结构体系为研究对象,介绍了强外框结构的受力特点,并研究了影响这一结构受力特性的主要因素。分析了内外框架柱的柱距对结构刚度和屈服承载力的影响,比较了同等抗侧刚度下不同结构的经济性和抗震性能。最后介绍了强外框结构在深圳太平金融大厦中的应用情况,结果表明在该项目中应用强外框结构比常规框架-核心筒结构体系节材10%以上。
Taking the reinforced outer frame structure system as the research object,the force characteristics of the reinforced outer frame structure were introduced,and the main factors affecting the mechanical characteristics of the structure were studied.The influence of the column spacing of the inner and outer frame columns on the structural stiffness and yield bearing capacity was analyzed,and the economic and seismic performance of different structures under the same lateral stiffness were compared.Finally,the application of the reinforced outer frame structure in Shenzhen Pacific Finance Building was introduced.The results show that the application of the reinforced outer frame structure in the project saves more than 10% of the material compared to the conventional frame-core tube structure system.
