A Nonlinear Model for Beam-Column Joint Based on OpenSees ...

The beam-column joint is the key component of a RC structure and also the hub of stress transferring between beam and column. It is the major part for ensuring enough stiffness, ductility and good energy dissipation capacity of the RC frame. In order to simulate the beam-column joints under cyclic loading, a model based on OpeeSees was studied.
