A Novel Shear Strengthening of Existing RC Shear Walls Using Steel Wire Mesh and Polymer Mortar

A new type of strengthening technique for existing reinforced concrete (RC) shear walls was proposed using steel wire mesh (SWM) and polymer mortar. The experimental campaign consists testing one conventional RC wall specimen four specimens strengthened different configurations ratios wrapping methods under cyclic lateral loading. results showed that the application meshes mortar not only delayed cracks formation but also effectively controlled crack propagation. average increase in cracking load about 79%. load-carrying capacity increased (about 55%) with considered reinforcement ratio compared to control specimen. Wrapping around surface prevented debonding layers, enhanced performance on exposed surfaces. theoretical expression estimate based softened strut-and-tie model. fairly predicted present previous study.
