Many materials are available for retrofitting masonry infill walls to resist explosion loads. Selection of the most suitable material is essential optimal performance and cost. In this study, a series trials were conducted in specially designed test setup determine compare performances 1/2-scale retrofitted with carbon fibre-reinforced polymer strips, steel wire mesh laminated bars, respectively, as well an unreinforced wall, subjected blast High fidelity FE models detail modelling brick, mortar also developed LS-DYNA simulate tests. The accuracy predicting field tests verified data. calibrated used perform intensive numerical simulations investigate effectiveness various measures. displacement response, failure mode, level damage fragmentation from both blasting compared assess results demonstrate that URM performed best among three measures loading resistance, wall closely spaced CFRP strips slightly better than bars.
