Hard projectiles can create both local impact damage and global dynamic damage in concrete structure. So, use of new reinforcing layers, which helps to concrete structures improvement against hard projectiles damage, has assigned large participation in experimental and numerical studies of defensive industries. In this paper, the behavior of high modulus aramid plates in strengthening concrete walls has studied with FEM software ABAQUS and effects of parameters like velocity of projectile, thickness of aramid layers and their arrangements have investigated. Results show salient increase of strength and reduction of deformation of reinforced concrete wall which strengthened with aramid against effect of projectile impact.<\div>

Up to now, seismic behavior of concrete structures has studied with experimental methods in laboratories and in numerical forms with uncoupled analytical and approximate relations. However, there is a need for coupled and numerical analysis of soil–structure for suitable investigating of seismic behavior of structure. In coupled analysis, because of considering soil–structure interaction effects and soil boundary conditions as a semi–infinite medium, results have well accordance with experimental results. One of the new materials which are used in strengthening concrete structures against loads is GFRP. In this paper, seismic behavior of reinforced concrete walls which strengthened with this material is studied as coupled with soil by FEM software ABAQUS and experimental studies are used for model verification. Results show significant reduction of deformation and increase in strength of reinforced concrete wall which strengthened with GFRP under seismic load.<\div>
