摘要：This paper studies the seismic performance of FRP-strengthened RC interior non-seismically detailed beam-wide columns and beam-wall joints after limited seismic *** eccentric and concentric beam-wide column joints and two beam-wall joints,initially damaged in a previous study,were repaired and tested under constant axial loads(0.1fc′Ag and 0.35fc′Ag) and lateral cyclic *** rapid repair technique developed,aimed to restore the original strength and to provide minimum drift *** repair schemes were characterized by the use of:(a) epoxy injections and polymer modified cementitious mortar to seal the cracks and replace spalled concrete;and(b) glass(GFRP) and carbon(CFRP) sheets to enhance the joint *** FRP sheets were effectively prevented against.possible debonding through the use of fiber *** between responses of specimens before and after repair clearly indicated reasonable restoration in strength,drift capacity,stiffness and cumulative energy dissipation *** specimens failed with delamination of FRP sheets at beam-column joint *** rapid repair technique developed in this study is recommended for mass upgrading or repair of earthquake damaged beam-column joints.
