Cyclic Performance Evaluation and Retrofitting of Coupling Double-Beam Constructed with Reinforced and Fiber-Reinforced Concrete: An Experimental and Numerical Study

Abstract

AbstractThis study investigates the seismic performance and deformation mechanism of coupling double-beams (CDBs) through experimental testing and numerical modeling. The proposed mechanism assumes that a CDB initially behaves as a conventional coupling ...Graphical abstract illustrating the experimental setup and cyclic performance of coupling double-beams with normal and steel fiber reinforced concrete and their retrofit with steel jacketing. Comparative hysteresis responses from experiments and validated ...
