In this research, using the Modified Compression Field Theory (MCFT), a new model is proposed to predict the behavior of reinforced concrete coupling beams. 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 and some nonlinear springs for considering bending deformations. I...

Abstract Testing of concrete panels subjected to pure in-plane shear loading is necessary elucidate the behavior concrete. However, available data for predicting capacity and steel fiber-reinforced are rather limited. This study aims evaluate made highly flowable strain hardening (HF-SHFRC) experimentally analytically, respectively, using a panel tester loaded under modified compression field t...

Abstract It is known that design deficiencies in shear are more dangerous than bending, as failures can occur a fragile way and without possibility of redistributing internal forces. Unlike bending design, designing for loads by different standards generate significantly results the same element, long models have been under discussion many years. This paper analyses evaluation behavior combined...
