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 ...
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. ...
For a beam–column joint with web openings, welding steel reinforcing plates onto the beam flanges is a relatively simple procedure. To prevent a reduction in the bearing capacity, the plastic deformation of the joint should be concentrated on the WO to avoid the joint fracture at the weld ...
Reinforced concrete earthquake-resistant frames are generally designed on the basis of “strong-column weak-beam”concept. Besides, shear failure of beam-column joints should be avoided in order that the frames exhibit adequate ductile performance. Joint shear failure occurs when the shear stress level...
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,...
Beam-column joints have been recognised as one of the potentially weaker elements of reinforced concrete moment-resisting frame structures when subjected t

The objective of this study is to point out an irrationality of the existing joint shear failure models for reinforced concrete beam-to-column joint. Test ... S Hitoshi - ASCE 被引量: 3发表: 1999年 , - ( An Experimental Study on Shear Capacity of Reinforced Concrete Exterior Beam-Column ...
[20] while the mode of failure of strengthened beam-column joints using steel jackets was flexural failure at the far edge of steel plates [12]. 3.2. Load-displacement records for the studied joint specimens Load-displacement records for the joint specimens are reported in Table 2. It can ...
Five specimens of the same dimensions, but different reinforcement details and different strengths of the material were cast in place to present a typical exterior beam-column joint of an RC building structure. With most of the gravity load sustained by interior and exterior gravity frames, the ...
