Load versus Displacement Validation between Ruaumoko Hysteresis Program and Experimental Work on CFRP Retrofitted Precast Beam-Column Exterior Joint

Abstract:

This paper presented the load versus displacement curve for experimental work and validated with modeling results. A full-scale specimen which representing retrofitted precast RC beam-column exterior joint with corbels was tested in the laboratory under reversible lateral cyclic loading until ±1.75% interstorey drift. The specimen was rehabilitated by using Carbon Fiber Reinforced Polymer (CFRP) wrapping method. Modeling work was carried out using Ruaumoko Hysteres Program. A curve representing load versus displacement for beam-column exterior joint is generated using Pampanin Reinforced Concrete Beam-Column Joint Hysteresis rule with reloading slip factor. The modeling result was compared with the load versus displacement curve obtained from experimental work. It was found that the hysteresis loops exhibited good agreement between experimental and modeling results. The effective stiffness, displacement ductility and equivalent viscous damping for the specimen were also discussed and compared.
