Glass Fiber versus Carbon Fiber Grid used in Textile Reinforced Mortar Strengthening of Precast RC Walls

Abstract—The experimental study presented hereis based on the seismic performance investigation of precast reinforced concrete wall panels (PRCWP), post-damage strengthening using different materials and different anchorage systems. Both wall panels have an initial small window opening, but the second panel has the opening enlarged into a large window opening in order to investigate also the cut-out effect. The behavior and failure details are presented and analyzed for both unstrengthened and post-damage strengthened situations. The economic aspect will also be discussed for each of the strengthening systems used.
