Nonlinear Finite Element Analysis of Exterior RC Column-to-Steel Beam Connection
A nonlinear three-dimensional finite element analysis of exterior RC column-to-steel beam (RCS) connection is performed by ANSYS finite element software. The numerical results, including the lateral load-drift relationship, lateral load-joint shear distortion relationship, shear stress distribution and effective width of the steel web at the last convergence substep, are compared with experimental results to assess the suitability of the finite element model (FEM) in predicting the ultimate response of RCS connection. The study shows that ANSYS FEM may simulate the behavior of exterior RCS connection under static loading very well, and good agreements are observed between the numerical and experimental results. Furthermore, the other static behaviors of exterior RCS connection, such as distribution of the minimum principal stress of the joint panel zone, concrete minimum principal stress-equivalent uniaxial strain relationship, story drift on the top end of the column and its component, the individual contribution of different elements to the joint shear capacity, and joint shear force-shear strain relationship, are investigated to gain more information and important data that can not be obtained in the experiment.
