本文采用有限元法分析了方钢管和圆钢管外钢管内钢管的钢管混凝土短柱的受压性能。不同的研究人员报告的一组测试数据被用来验证有限元建模。给出了钢管混凝土短柱的平均应力-纵向应变曲线、混凝土应力分布、混凝土与钢管的相互作用以及空心率对钢管混凝土短柱性能的影响。研究了影响组合柱截面承载力的重要参数。(C)2009爱思唯尔有限公司保留所有权利。
This paper reports a finite element analysis of the compressive behaviour of CFDST stub columns with SHS (square hollow section) or CHS (circular hollow section) outer tube and CHS inner tube. A set of test data reported by different researchers were used to verify the FE modelling. Typical curves of average stress versus longitudinal strain, stress distributions of concrete, interaction of concrete and steel tubes, as well as effects of hollow ratio on the behaviour of CFDST stub columns, were presented. The influences of important parameters that determine sectional capacities of the composite columns were investigated. (C) 2009 Elsevier Ltd. All rights reserved.
