In this research, the effects of different repairing materials and techniques used on damaged Masonry walls under an in-plane lateral loading were investigated. Seven clay brick walls with dimensions of (1200 × 935 × 115) mm were tested. The walls were tested until a visible crack was observed, later repaired, and tested again up to failure. The repairing materials consisted of grid configured strip materials (metal, plastic, flat webbing 'textile' and wild cane 'organic' strips), near surface mounted (NSM) steel re-bars and steel wires in mortar joints. Based on the experimental results, the repairing materials/techniques restored the shear strength by about 48–103% of the original strength. The ductility factor of the repaired walls ranged from 4.5 to 48.3 (flat webbing 'textile' highest). The energy dissipation ratio of the repaired walls ranged from 4.3 to 12.7 (flat webbing 'textile' highest). Prediction equations for shear strength are presented giving reasonable results compared to the experimental results. [ABSTRACT FROM AUTHOR] |
