| Abstract: | A single-room, single-storey full-scale brick masonry building with precast RC roofing system was tested thrice under displacement
controlled lateral cyclic loading, to assess the effectiveness of the basic repair and seismic strengthening techniques. Initially,
the virgin building specimen was loaded laterally to failure. In the second stage, the damaged building was repaired by stitching
across the cracks, and tested under the same lateral loading. In the third stage, the twice-damaged structure was repaired
once more by stitching and strengthened by twin lintel belt in steel and vertical corner reinforcement, and re-tested. The
building strengthened bytwin lintel belt in steel showed about 28% higher strength under lateral loading than the virgin building. |
