Overview

Randomized trial shows improved shear resistance in masonry, highlighting effective remediation for damaged structures.

Key Points

  • The aim is to evaluate the effectiveness of a hybrid composite reinforced mortar system in enhancing the structural integrity of existing masonry.
  • Diagonal compression tests on unreinforced masonry panels using a 25 mm natural hydraulic lime-based mortar with a 20 × 20 mm AR glass grid.
  • Comparison of shear resistance and stiffness before and after strengthening.
  • Retesting of previously damaged masonry panels to assess recovery of shear capacity.
  • Average shear resistance increased by 32% in strengthened panels compared to original unreinforced masonry walls.
  • Average shear stiffness was preserved after strengthening.
  • Retested specimens recovered up to 98% of their original shear capacity post-repair.
