摘　　要：节点是结构的关键部位,也是设计、施工的难点,其受力性能特点是众多工程师关注的焦点。采用ABAQUS有限元软件,研究混凝土强度、梁柱节点核心区的截面高度、核心区的梁柱截面宽度比等因素对矩形钢筋混凝土框架梁柱节点受力性能的影响程度。经过研究发现,提高混凝土强度等级对改变节点的受力性能效果较为明显。为解决梁柱节点核心区抗剪超限问题,提供了有效参考价值。A joint is not only the key component of a building,but also the difficulty in designing and construction.Due to its significance,mechanical behavior of joint of column and beam becomes the research focus.Researches are carried out on the influence of concrete strength,the ratio of beam-column section width and width of the cross section with the finite element software ABAQUS.It's found that improving the concrete strength has a significant effect on the difference of the mechanical behavior of the joint.It's hoped that this paper provides an effective reference for solving the supre-shearing problems in the core area of the beam-column joints.
