This study aims to develop a new concrete structure by using the advanced PBO fiber meshes as a shear strengthening material inside concrete structural elements. The experimental parameters include the number of PBO fiber mesh layers and the width of PBO fiber meshes in the shear span. The results revealed that increasing the number of the PBO fiber mesh layers can increase the shear capacity of the RC beams, however, the shear capacity will be reduced if the strengthened width of the PBO fiber meshes is over than the effective width in the shear span.
