Verification of Experimental Hysteresis Loops for Exterior Beam-Column Joint Under Lateral Cyclic Load

This paper presents the verification of experimental to modelled hysteresis loops for exterior beam-column joint tested under lateral cyclic loading. The reinforced concrete exterior beam-column joint was designed using Eurocode 8 and equipped with fuse bars as energy dissipators. The specimen was tested under lateral cyclic loading under controlled displacement (drift). The purpose of this study is to ensure a good agreement from both works is achieved. The exterior beam-column joint modelled hysteresis loops were carried out using HYSTERES Program which is one of the modelling programs under the Ruamoko 2D program. The verification was done by comparing the parameters of experimental hysteresis loops to modelled hysteresis loops. The response of the specimen was compared in terms of equivalent viscous damping, stiffness and ductility. Low percentage differences indicate good agreement between the two hysteresis loops.
