斜柱转换与桁架转换在某高层钢结构中的比较分析
|
摘要
斜柱转换作为一种新型的转换形式,在高层混凝土结构中已有初步应用,并获得了良好的结构性能和明显的经济效益。以某高层钢结构大楼为工程背景,对比分析了斜柱转换和桁架转换对结构性能的影响,研究了斜柱转换层内主要构件的受力特点。分析结果表明:两种转换形式的结构基本动力特性及地震响应基本一致,均可满足规范要求;转换斜柱可按直立柱进行设计计算;对转换梁除要进行强度计算外还须重点验算其稳定性;斜柱转换综合经济效益更好。斜柱转换应用于高层钢结构是可行的、经济的,可为其推广应用提供参考。
As a new transferring form,inclined column transfer has been applied in a number of high-rise concrete structures and exhibits good structural performance and economy benefit.This paper takes a high-rise steel structure building as an example to compare structural performance between inclined column transfer system and truss transfer system.The analysis results indicate that dynamic response and seismic behavior of the structure are similar for both transfer systems,and they both meet the design requirements of current standards.The inclined column can be considered as a vertical column in the design.For transfer beam,both ultimate capacity and stability should be checked in the design. Also,the inclined column transfer system can achieve better economy benefit than that of truss transfer system. Overall,the inclined column transfer system is applicable and economical in high-rise steel structures.This paper provides a reference for the design and application of inclined column transfer system in high-rise steel structures.
