Abstract
In this research, using the Modified Compression Field Theory (MCFT), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. The model is able to consider the effects of shear and axial forces and bending moment, simultaneously. The proposed model includes a nonlinear shear spring, an axial spring, two inclined truss members and some nonlinear springs for considering bending deformations. The results of the proposed model were compared with several test results conducted by the authors and other researchers. The comparison shows that the proposed model can predict shear behavior of coupling beams, appropriately.
