Capacity analysis of exterior beam-column reinforced concrete joints using Midas FEA software

Abstract

One of the main parts in the planning of reinforced concrete structures lies in the beam column joint (BCJ) connection. The beam-column connection consists of interior, exterior, and knee joints. In this study an analysis has been carried out regarding the behavior of the joints on the exterior of the beam-column joints and look for the capacity of the structural strength of the beam-column using conventional methods. The connection type component will be carried out based on the results of laboratory test results and modifying the connection type based on the data search obtained, then compared with the Midas FEA Software. The results of the analysis of the capacity of beam-column joints based on ASCE 41 and finite elements in the yield condition yield smaller values with a difference of 1.34% - 4%. In the inside hook modification using laboratory and finite element test methods, the difference in capacity values is greater, namely 2.91% - 8.12%. The behavior of the beam-column joints capacity when two U-bar joint shear reinforcement was added did not increase significantly by 2.77% and the behavior of the beam-column joints when four U-bar joint shear reinforcement was added showed a high increase by 95.26%.
