摘　　要：利用有限元软件Abaqus模拟顶底角钢连接节点,分析连接节点的弯矩转角性能和初始刚度,提出了一种计算初始刚度的新模型.将通过新模型与Kishi和Chen提出的初始刚度计算公式获得的数据进行对比,结果表明前者具有较好的计算精度.Top-seat angle connection is one of frequently used beam-to-column connections in engineering.For a deeper understanding of the mechanical behavior of top-seat angle connection,finite element software-Abqaus is utilized to analyze their moment-rotation performances and to study the initial stiffness.The computational formula of initial stiffness of top-seat angle connections is thus put forward.Comparison of the data obtained from the proposed formula with the existent data shows that this formula has better precision and shows good agreement with test data.This result provides a reference for engineering design and applications.
