COMPARATIVE STUDY ON BEHAVIOR OF REINFORCED CONCRETE FRAMES WITH DIFFERENT BEAM- COLUMN JOINTS

A beam-column joint is a very critical zone in reinforced concrete framed structure where the elements intersect in all three directions. There are practical difficulties involved in the construction of reinforced beam-column joints. In this review to focus on the general behavior of reinforced concrete Beam-Column joints (BCJ) exterior, interior and at top floor. Previous research work presented studying BCJ under gravity and seismic loads in addition to the effect of many parameters on the mechanical behaviour of BCJ the effect of reinforcement configuration, eccentricity, the joint aspect ratio (hb/hc), concrete compressive strength, and the compressive column axial load. BCJ classification was introduced according to ACI 318-02 (2002) and Egyptian code (2007), the equations and recommendations related with BCJ in national codes were reviewed. This study presented a comparison between the deflection and the static load capacity that can be received by the connection of reinforced concrete beam-column which is monolithically connected and non- monolithic.
