PUSH-PULL TESTS ON A REAL MASONRY-INFILLED RC BUILDING
Results from lateral-loading inelastic tests on a real masonry-infilled reinforced concrete building are presented and discussed. The first test has been carried out on the original building. Extensive damage to both masonry infill panels (MIPs) and reinforced concrete elements (columns and staircase structure) has been produced, with out-of-plane collapse of almost all the walls parallel to the loading direction. The second test has been carried out on the repaired building.Namely, perimeter MIPs were completely rebuilt and also strengthened by placing fiber reinforced polymer (FRP) rods into the mortar bed joints of masonry. The FRP system was applied with the basic aim to change the failure mode from diagonal tension to shear sliding. Experimental results show that this objective was successfully achieved. Extensive damage was produced also during this second test to all building components. Besides, back-analysis of experimental results has been carried out using simple analytical models including contribution from the staircase structure and the MIPs.
