Study on the Behaviour of Exterior Beam-Column Joint Using Crossed-Rebar with Prestress

Surumi Nazar, Sujisha.V

Abstract: Beam-column joint is the gap in the modern ductile design of building. Especially under the Earthquake loading this is more susceptible to damage. Due to brittle nature of failure this type of failure cannot be afford. Due to cross pre stressing there is increase in the shear strength of the concrete in the joint core. A model can be formulated to calculate the increase in shear strength of the joint core using ANSYS. The increase in the performance of the joint due to cross-pre stressing which may leads to the decrease in the joint confinement reinforcement. Further a formulation can be generated to calculate that how much reinforcement can be reduced due to this cross-pre stressing. Here it is combine the benefits of the crossed rebar and pre stressing in the joints together. The present work is divided into two phase. First phase for modeling a frame using STAAD and find out the critical exterior joint. The ANSYS model is created with pre stressing force through rebar is being applied at the joint with the help of the steel plates acting as the bearing.

Keywords: Beam-column joint, Crossed-Pre stress rebar, STAAD PRO, ANSYS
