Parametric Analyses of the Response of Masonry Walls with Reinforced Plaster

This paper presents the results of a parametric study on response unreinforced and retrofitted masonry specimens. The adopted strengthening technique is steel-reinforced plaster, which very commonly used but it not supported by proper theoretical experimental characterization in scientific literature. aim was to investigate main parameters that affect structural performances walls. Several numerical models were implemented using finite element method analyze influence bricks’ arrangements, mechanical properties mortar joints, number connectors, thickness plaster coating. A concrete damage plasticity model describe bricks, behaviors. For specimens, outcomes confirmed strength had significant performance wall, together with presence potential weaknesses while bond effect negligible. reinforced walls, connectors do have wall capacity may prevent instability if considered. Furthermore, coating does collapse load significantly, increasing fracture energy, can be produced, for instance, fiber-reinforced concrete, increases more limited damage. Finally, an increase beneficial terms load, even though greater seismic masses significantly.
