Abstract
Beam and column where intersects is called as joint or junction. The different types of joints are classified as corner joint, exterior joint, interior joint etc. on beam column joint applying quasi-static loading on cantilever end of the beam. and study of various parameters as to be find out on corner and exterior beam column joint i.e. maximum stress, minimum stress, displacement and variation in stiffness of beam column joint can be analyzed in Ansys software ( Non-Linear FEM Software) Significant experimental research has been conducted over the past three decades on hysteretic behavior of beam-column joints of RC frames under cyclic displacement loading. The various research studies focused on corner and exterior beam column joints and their behavior, support conditions of beam-column joints. Some recent experimental studies, however, addressed beam-column joints of substandard RC frames with weak columns, poor anchorage of longitudinal beam bars and insufficient transverse reinforcement. the behavior of exterior beam column joint is different interior beam-column joints by Nonlinear finite element analysis using ATENA a software for nonlinear analysis of reinforced concrete structures. The model has been calibrated using the results of the third authors tests. The behavior of exterior and interior beam-column turned out to be different .The parameters influencing the shear strength are not the same for both types of connections. Different parameters like effect of the material properties, effect of geometry of connection, effect of reinforcement, effect of concrete compressive strength and joint slenderness. The parameters influencing the shear capacity are different for exterior and interior connections. The FE results were compared with the authors experimental results and the good agreement between the two was achieved. Kuang J.S. and Wong H. F. (2 ) Reversed cyclic-load tests are carried out on full-scale reinforced concrete (RC) exterior beam-column joints, which are fabricated to simulate those in as-built RC framed buildings designed to BS 8110. Emphasis of the study is placed on the effects of the types of beam bar anchorage and location of laps in column reinforcement on the seismic behavior and shear strength of RC exterior joints subjected to simulated earthquake load. Shear strength of a beam-column joint predicted by the criterion of initial diagonal cracking is highly dependent on the level of axial loads applied on the column; this model gives very good correlations with all the test data in this study
