  • Abstract This experiment was mostly aimed at the feasibility of retrofitting non-ductile and low-strength interior beam-column joint by Concrete Jacketing and Steel Jacketing, and a discussion was made through the differences in stiffness, ductility, and joint shear degradation between benchmark and retrofitted specimen.
    In the respect of ductility and energy absorption, JI2 Concrete Jacketing and JI4 Steel Jacketing schemes could both prevent benchmark from unexpected joint shear failure before beam plastic hinges developed and respectively upgraded its own ductility by 30% and 77%. However, both JI2 and JI4 specimen’s failure modes are joint shear failure at the end of the test, and their retrofitted ductility did not reach 4, which is the target of our retrofitting scheme. Therefore, further research is needed.
    Finally, according to the discussed behavior of joint shear degradation, we provided beam-column joint retrofitting scheme recommendations, which can be referenced for further research on beam-column joint retrofitting in Taiwan.
