In the second phase two exterior beam-column joint from previous experimental programme. They were model and analyse using ANSYS v13. Improvement in the ultimate load and failure pattern has been detailed in the thesis. From this phase we come to conclusion that this new technique is more ...
New concepts of ultimate moment capacity and moment at balanced failure of beam-column joints are defined. The upper bound value of reinforcement precluding joint failure before yielding of longitudinal reinforcement is also defined. In addition, this paper demonstrates how the concepts are used to ...
Beam-Column Joints in a reinforced concrete moment resisting frame are crucial zones for transfer of loads effectively between the connecting elements (i.e. beams and columns) in the structure.The three main factors considered in design of a Beam -Column joint are Anchorage of main reinforcement ...
A new analytical models for joint shear failure of reinforced concrete exterior beam-column joints is proposed. It is used for predictidction of strength and failure modes and it is extended from a model for interior beam-column joints by the author. The model contains no empirical factors acco...
(RC) frame structures are implemented by either static pushover analysis (PA) or dynamic time history analysis, with diverse settings of the plastic hinges (PHs) on such main structural components as columns, beams and walls, the complex behavior of shear failure at beam-column joints (BCJs)...
The failure modes, mechanical properties, and resistance mechanisms of beam–column substructures with welded flange-bolted web connection in the minor-axis direction under different span ratios (1:0.6, 1:1.0, 1:1.4) were compared and analyzed under the condition of progressive collapse. The beam–...
this paper is a new technique proposed for repairing reinforced concrete beam-column joints that have been failed first under lateral cyclic loads; and then repaired using high performance fiber reinforced cementitious composite jackets all around the joint column regions; and retested up to failure. ...
The purpose, though, of the present work is the investigation of the influence of the inelastic response and degradation of the exterior beam–column joints on the seismic behaviour of multi-storey RC frames with and without infills accounting for the joint degradation effect [15]. Furthermore,...

PURPOSE:To enhance the strength of a column beam joint part by protrudingly providing upper and lower two-stage connecting reinforcements on the connecting end surface lower part of a beam, with the lower stage reinforcement being long, and the upper stage reinforcement being short, and further ...
