Top-seat angle connection is one of normal used beam-to-column connections in engineering.For grasping the mechanical behavior of top-seat angle connections more deeply,finite element software- Abqaus is utilized to analyze the moment-rotation of top-seat angle connections,to studythe initial stiffness of the connections and toraise the formulationof initial stiffness of top-seat angle connections.Finally,the available experimental data are compared.The study result shows that the proposed formulation of initial stiffness of top-seat angle connections has better precision,and it shows good agreement with test data.Hence,the result provides a referencefor engineering applications.

Key words: finite element method, top-seat angle connections, initial stiffness
