Abstract
This study aims to determine the experimental crack propagation pattern on non-monolithic exterior reinforced beam-column joints with strengthening. The strengthening provided is in the form of a pedestal plate installed on the column and notch at the interface between the beam and column. Broken steel pipes used as a sleeve that connects the reinforcement extending from the column to the beam. Four sets of specimens were made to represent each monolithic connection, non-monolithic non-strengthening joints, and non-monolithic joints with strengthening. All specimens tested with a single static load. Monolithic beam-column joints used as control specimens against crack propagation patterns in the non-monolithic beam-column joints. The results showed that the decrease in performance and strength due to the non-monolithic connection in the beam-column joints could improve by giving a pedestal plate and notch. This strengthening can increase peak load capacity to reach 99%. The non-monolithic joint stiffness can also be fixed up to 90% compared to the monolithic beam-column joint, the crack pattern that occurred also improved through of crack width and crack rate.
