Seismic Response of Steel Fibre Reinforced Concrete Beam-Column Joints

The present research work aims to investigate numerically the behaviour of steel fibre reinforced concrete beam–column joints under seismic action. Both exterior and interior joint types were examined and 3D nonlinear finite element analyses were carried out using ABAQUS software. The joints were...

Civil engineering (General) The present research work aims to investigate numerically the behaviour of steel fibre reinforced concrete beam–column joints under seismic action. Both exterior and interior joint types were examined and 3D nonlinear finite element analyses were carried out using ABAQUS software. The joints were subjected to reversed-cyclic loading, combined with a constant axial force on the column representing gravity loads. The joints were initially calibrated using existing experimental data – to ascertain the validity of the numerical model used – and then parametric studies were carried out using different steel fibre ratios coupled with increased spacing of shear links.
