Plane Flexure

Near-surface mounted (NSM) reinforcement is used to retrofit masonry structures for increased strength and resiliency; however, its application to new masonry construction remains largely unexplored. Four masonry walls measuring 3.2m tall were constructed from hollow concrete blocks to assess the potential of NSM reinforcement to increase flexural stiffness. Two of the walls were reinforced conventionally, and two were reinforced with NSM bars. Each wall had a total area of steel reinforcement of 600mm2 and was loaded under conditions of third-point out-of-plane flexure. All four walls had similar flexural strength, ranging from 24kNm to 26kNm; however, the stiffness (determined using direct measurement of curvature, curvature calculated using conditions of equilibrium and compatibility, and the load displacement response) of the NSM reinforced walls was twice that of the walls with conventional reinforcement. The flexural stiffness of the masonry walls was underestimated by current Canadian design standards provisions under low out-of-plane loads.

Optimum Solution

Numbers of residential houses were damaged in some areas caused by earthquakes. The damages greatly affected the number of losses. Most of the houses in some countries are made of brick unreinforced masonry (URM) walls. Improving the structural performance of this kind of masonry has become important. For this reason, experimental study was conducted on the flexural performance of brick walls retrofitted with strapping band (polypropylene/pp-band). The walls were constructed using bricks produced manually with joint mortar ratio of 1 PC: 6 sand, that chosen to represent the actual field conditions of the communities in Indonesia. The aims of the study were to determine the out of plane flexural performance of the non-retrofitted and retrofitted brick masonry walls under cyclic loading by using some variations of the distance between pp-band. The walls were loaded to produce flexural bending that caused vertical and horizontal cracks. The results of the test showed that the retrofitted walls failed by large deformation. After crack, the strength reduced to about 25-50% of the crack load and then regained progressively as residual strength until 150% higher than the strength at crack load by large deformation due to the strapping band mesh. The wall with 10 cm pp-band distance should be used as optimum solution for retrofitting
