  • Along with the massive number of earthquake disasters that occurred and have an impact on the collapse and damage of a building structure, making repairs and strengthening of a structure become a common thing in the field especially in precast joint structure components which often experience a decrease in strength or even malfunction so that they are no longer able to withstand the load of a building. Along with the development of strengthening methods used in structural reconstruction work, there is a need for an evaluation model that can provide results to help develop models in structural strengthening. This study aims to evaluate the model of strengthening on dry joint in precast column and beam using CFRP materials by analyzing the maximum capacity values and behavior of structural strengthening such as ductility and stiffness with the loading method quasi-cyclic. The strengthening model used in this discussion is divided into 2 strengthening model variants including (a). steel plate + CFRP sheet and (b). CFRP plate + CFRP sheet which is attached to the concrete surface with the aid of glue (epoxy). The results of the testing of strengthening with the model steel plate + CFRP sheet show the results of maximum capacity values, ductility and stiffness higher than the models with material CFRP plate + CFRP sheet.
