STRENGTH AND DUCTILITY OF CAST-IN-PLACE BEAM-COLUMN JOINTS

摘要: The results of an experimental study the behavior cast-in-place reinforced concrete beam-column joints, subjected to slow load reversals simulating seismic loading are presented. Variables were amount and size joint reinforcement, stress vs. strain characteristics steel. It was found that history does not affect strength but seriously affects stiffness sub-assemblies; ACI equation predicts cracking shear well 45 degree truss analogy predict joints. Stress characteristic steel has a significant effect on confinement provided energy dissipating capacity beams depends significantly anchorage at To ensure plastic hinge is formed in beam, column flexural should be based core alone.
