| 摘 要： | 为了深入研究用双重环筋加强的节点区柱钢管不连通式钢管混凝土柱-梁节点的力学性能,采用TNODIANA软件对其进行参数化非线性有限元分析,并与试验结果进行了对比研究.结果表明,当节点高度不太低时,非线性有限元分析可以较好地模拟节点区的受力变形、极限承载力、裂缝开展及钢筋应变分布规律.混凝土强度、钢筋配筋率及环梁宽度的提高均会使得节点的轴压承载力提高,其中混凝土强度的影响程度最大,钢筋配筋率次之,环梁宽度更次之. |

| Abstract: | In order to study the mechanical behavior of concrete-filled steel tubular column-beam joint strengthened by double layer steel ring bars with discontinuous steel tube in the joint zone,TNO DIANA software was used to carry out the nonlinear finite element analysis on the joint.The results are compared with the experimental results.It shows that when the height of the joint is not so low,the nonlinear finite element analysis can simulate the deformation,bearing capacity,crack development and the stress distr... |
