摘要：
A single-room,single-storey full-scale brick masonry building with precast RC roofing system was tested thriceunder displacement controlled lateral cyclic loading,to assess the effectiveness of the basic repair and seismic strengtheningtechniques.Initially,the virgin building specimen was loaded laterally to f;ilure.In the second stage,the damaged buildingwas repaired by stitching across the cracks,and tested under the same lateral loading.In the third stage,the twice-damagedstructure was repaired once more by stitching and strengthened by twin lintel belt in steel and vertical comer reinforcement,and re-tested.The building strengthened by twin lintel belt in steel showed about 28% higher strength under lateral loadingthan the virgin building.
