Nonlinear Finite Element Analysis of Welded Connection of Three Steel Beams to Lateral Reinforced Concrete Column

To facilitate the analysis, design and construction process of RCS frames (Reinforced concrete columns and steel beams), this paper introduces a type of rigid beam to column connection and discusses its seismic behavior obtained from finite element analysis using Opensees software. The study shows that Opensees may simulate the behavior of exterior RCS connection under static reversed cyclic loading very well ,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 are investigated to gain more information and important data that can not be obtained in the experimental studies
