Seismic retrofit of deficient 3D RC beam–column joints using FRP and steel PT rods

The purpose of this paper is to evaluate the behavior of vulnerable joints of substandard RC frames, improved by two different methods, 1- Shear and flexural retrofit of beam–column joints using FRP sheets 2- Enlargement of beam–column joints using angles and pre-tensioned rods. In this study the be...
