Abstract :

Most of the RCC failures commonly occur due to inadequate detailing or model design of joints. The fundamental requirement at joints is to ensure that all forces acting at the ends of the members are effectively transmitted through the joint to the supporting members. The junction of beams and columns experiences complex stresses that must be carefully addressed during the design of reinforcement. The main focus of this paper is to evaluate the effectiveness of different types of corner joints with various reinforcing patterns compared to the conventional one. For this purpose, a total of 12 joints divided into 4 categories with 3 different ultimate concrete compressive strength were analyzed. Here the categories are namely Model 1, Model 2, Model 3 & Model 4. These joints are modeled using ANSYS default CAD software SPACECLAIM and analyzed using ANSYS. It is observed that the ultimate load-carrying capacity is the highest for model 2 than all other models. In comparison based on ductility, in most of the comparisons model 2 shows higher ductility than others and the relationship was found as Model 2>Model 3> Model 4> Model 1. In addition, with respect to elastic and plastic regions, model 2 shows more elastic and plastic regions. Finally, it can sustain more load than the other joint Reinforcement (RF) pattern with respect to the same displacement. Considering all those results, Model 2 can be proposed to be used as an alternative to Model 1 i.e., an alternative for conventional RF pattern.
