本文对方钢管混凝土构件在荷载和氯离子腐蚀共同作用下的受力性能进行了有限元分析，所建立的有限元分析模型与试验结果进行了对比验证。2012）[1]。利用有限元模型对钢管混凝土短柱和梁在荷载和氯离子腐蚀共同作用下的受力性能进行了机理分析。对荷载-变形关系进行了全过程分析。最后，在参数分析的基础上，给出了钢管混凝土短柱和短梁在长期荷载和锈蚀作用下强度的简化计算方法。(C)2013爱思唯尔有限公司保留所有权利。
This paper presents a finite element analysis (FEA) on concrete filled steel tubular (CFST) members with square sections under both loading and chloride corrosion, the established FEA model was verified by the experimental results presented in the companion paper (Han et al., 2012) [1]. The FEA model was then used to perform mechanism analysis on the CFST stub columns and beams subjected to both loading and chloride corrosion. Full-range analysis on the load versus deformation relations was carried out. Finally, simplified methods for calculating the strength of CFST stub column and beam under long-term loading and corrosion were illustrated based on the parameter analysis. (C) 2013 Elsevier Ltd.
