【摘要】：随着社会经济的进步,现代新型建筑向着超高层、大体量、多功能与复杂化发展。为了满足新型的建筑设计方案和多功能的使用要求,结构转换层越来越多的用于结构设计中。其中,桁架转换层杆件尺寸的确定以及在地震作用下的内力分析需要进行重点研究。本文主要研究了空腹桁架转换层与斜杆桁架转换层。本文首先运用SATWE软件对两种形式的桁架转换层进行受力、配筋以及挠度裂缝的对比分析,确定各杆件的适宜尺寸;之后,通过对结构的基本动力特性分析和反应谱分析,分析对比了两种形式转换层基本周期、地震作用下的位移以及内力区别;最后,运用通用有限元软件SAP2000对两种结构进行静力弹塑性分析,分析对比带有不同形式转换层的结构塑性铰出现顺序以及抗震性能评价。通过本文的研究成果,可以对类似建筑结构设计提供参考。
[Abstract]:With the progress of society and economy, the modern new building to high-rise, large volume, multi-function and complicated. In order to meet the requirements of the use of architectural design model and function of the design for the structure layer structural transfer more and more. The truss conversion layer bar size and determination of the internal force under the earthquake the analysis needs to focus on. This paper mainly studies the vierendeel truss transfer layer and diagonal truss transfer layer. This paper uses layer truss SATWE software for the two kinds of reinforcement and crack deflection analysis, comparison, to determine the appropriate size of the rod; then, through the basic analysis of dynamic characteristics and response on the structure of the spectrum analysis, comparative analysis of two forms of conversion layer basic cycle, under the action of earthquake displacement and internal force difference; finally, by using the general finite element software SAP2000 on the two The structure is analyzed by static elastoplastic analysis. The occurrence order and the seismic performance evaluation of plastic hinge with different transfer storey are analyzed and compared. Through the research results in this paper, we can provide reference for similar building structure design.
