Abstract
The formation of plastic joints in the reinforced beam-to-column joint is influenced by a number of factors. The behaviour and location of this joint is of major importance since it defines the overall performance of the rigid framework when subjected to loading. Mandated by the majority of codes and standards, the strong-column weak-beam philosophy is used and recognized by the formation of this joint in the beam. This study looked into the effect of reverse loading to the behaviour of plastic joints as compared to a monotonic loading protocol. The study analysed the load-deformation behaviour and ultimate load carrying capacity while additional information is collected through visual observation on the failure and cracking pattern. The study concluded that the reverse loading negatively influenced the load carrying capacity, but negligibly affected the overall behaviour of the joint.
