Abstract:
Confinement introduces deformability in reinforced concrete structural elements. The
relationship of stress and strain in confined concrete is appreciably affected by the yield
strength, arrangement of reinforcement and confining/ transverse reinforcement spacing.
Performance of confined reinforced concrete components can be studied through their loaddisplacement
response curves. Parameters such as yield strength, peak load, ultimate
displacement, stiffness degradation and ductility can all be evaluated from these curves. The
hinge zones of beam and columns, in reinforced concrete frames, are often well confined.
However, higher ductility requirements of the system can only be met if the stress path of
moment reversals occurring at the face of supports exists through the joint. The joints are
often congested. An interior joint, of intermediate floor, is required to accommodate
reinforcement of at least six structural components. Due to congestion it is difficult to add
confining reinforcement in the joints. In this project, a proposed technique to confine beamcolumn
joints using steel strips will be implemented and examined.
