本文研究了钢管混凝土轴心受拉构件的受力性能。报道了13个试件的实验结果。试验变量为钢管直径、内钢管混凝土与外钢筋混凝土构件的粘结状态。通过推出试验研究了钢管混凝土与钢筋混凝土的粘结性能。建立了有限元模型，对钢管混凝土受拉构件的受拉性能进行了分析。研究了钢管混凝土与混凝土的相互作用、钢管混凝土与核心混凝土的相互作用、钢管混凝土与核心混凝土的相互作用以及钢管混凝土与核心混凝土的相互作用。核心混凝土与钢管共同工作，钢管的抗拉强度因“复合效应”而提高，而外部钢筋混凝土构件与内部钢管混凝土构件分离，从而使钢管的抗拉强度提高。
AbstractThis paper studies the behavior of concrete-encased concrete-filled steel tube (CFST) members under axial tension. Experimental results of thirteen specimens were reported. The variables in the test were the diameter of the steel tube, bond condition between the inner CFST and outer reinforced concrete (RC) components. Push-out tests were conducted to investigate the bond performance between the inner CFST and outer RC components. A finite element model (FEM) was then developed to perform further analysis on the tensile behavior of the concrete-encased CFST member. The internal load distribution between the inner CFST and outer RC components, the interaction between the core concrete and steel tube, and the interaction between the outer concrete and steel tube were investigated. The core concrete and steel tube worked together well, and the tensile strength of the steel tube was enhanced because of the “composite effect,” while the outer RC component was separated from the inner CFST and thus work...
