Triplet Shear Tests on Brick and Pumice Blocks Strengthened by Seismic Textile

The goal of this study is to evaluate the shear capacity and the crack pattern of the masonry building units after reinforcing application. Experimental researchs were executed to indicate the effect of strengthening by using the seismic fabric and the relevant specific plaster consisting of expanded glass granular. The reinforcement system is formed both multiaxial textile comprising of alkali resistant glass-polypropylene fibrous and mentioned plaster. For triplet shear tests on perforated bricks and pumice blocks a total of twelve specimens were produced. The plaster having thickness of 2 cm and reinforcing fabric was applied only unilaterally of the samples. All experiments in this study were performed at Sakarya University’s structural mechanics laboratory. The displacement-measuring feature of the vertical load-controlled cylinder with a force capacity of 50 kN and a loading speed of 1.5 mm/min was used to obtain information about the amount of slip and cracking behavior occurring in the block-mortar interface due to shear stress. The results of this experimental study were compared in terms of forcedisplacement relationships for all test samples. It was detected from the final situation of all non-retrofitted specimens had a slip failure along the element-mortar interfaces. It is concluded that the ductility capacity and shear strength increased considerably via seismic fabric and relevant plaster combination
