Introduction Concrete is widely used as a primary structural material in construction due to numerous advantages, such as strength, durability, ease of fabrication, and non-combustibility properties, it possesses over other construction materials.
Fire resistance and thermal behavior after exposure to a fire in the concrete structure depends on thermal and mechanical properties of concrete materials.
Materials and Methods Steel Fiber.
This is due to the steel fiber resist in concrete and there is a good bonding between materials and reinforcement that lead the crush occurred slowly.

The Deep Surface Rolling (DSR) technology can substantially increase the fatigue life of metallic materials due to the introduction of deep compressive residual stresses in the material surface.
Mechanical peening using steel shot, glass or ceramic beads has been demonstrated to improve the fatigue life of metallic materials, due to the compressive residual stresses introduced into the material surface to a depth of about 0.25 mm.
