The damage of the masonry infill walls under the blast loading is serious, and the blast-resistant design of masonry infill walls become a hot topic. From the microcosmic and macroscopical analysis, the blast performance of the BFRP-FRCM reinforced masonry infill walls will be systematically studied by means of theoretical analysis, experimental research and numerical simulation. The dynamic performances of the BFRP mesh, FRCM and BFRP-FRCM composite layer will be revealed, and a BFRP-FRCM composite layer model considering strain rate effect will be set up. A static and dynamic bond-slip constitutive model on the interface of the BFRP mesh and FRCM, the interface of the BFRP-FRCM and masonry infill walls will be established. Bond-slip mechanism of the interfaces between different materials of the BFRP-FRCM composite layer reinforced masonry infill walls will be revealed. The failure modes of the BFRP-FRCM reinforced masonry infill walls under blast loading will be studied, and effect rules of composite layer parameters influencing blast-resistance properties of masonry infill walls will be set up. The blast-resistance reinforcement mechanism of the BFRP-FRCM on masonry infill walls will be revealed. The blast-resistance performance evaluation and blast-resistance design method of the BFRP-FRCM strengthened masonry infill walls will be established, and the achievements could become the basis for the safety protection of masonry infill walls.
