| 摘 要： | 基于文献[1]钢管混凝土结构施工安全性的研究思路,建立了多层钢管混凝土框架中的空钢管结构施工受力分析的有限元模型。以一12层钢管混凝土框架结构为例,分析框架结构中的空钢管在施工荷载作用下的受力特点,研究了钢管应力和变形的发展规律,在此基础上初步探讨了不同施工方案的影响。

| Abstract: | Based on the method of construction safety analysis on hollow steel tube of concrete filled steel tubular(CFST) frame structures previously presented by reference[1],a finite element analysis(FEA) modeling was introduced and performed for hollow steel tubes in a 12-storey CFST frame structure under construction loads.The stress and deformation of the steel tubes were analyzed by using the FEA modelling.Finally,the influence of different construction schemes of the CFST frame structure was discussed primaril... |
