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. mm), while two cycles per drift were made. The test was stopped when the specimen lost 20% of its load bearing capacity. The boundary conditions consist of restrained rotation and out of plane displacement prevention (1). The compressive strength (cubic measured) for the panels was 27.25 MPa for the PRCWP (10-L1) specimen and 27.25MPa for the PRCWP (11-L1/L3) specimen. The instrumentation part in the experimental test consisted of three measuring quantities, namely displacements using displacement transducers, unit strains (using strain gauges) and forces (using piezo-resistive transducers).
