Impact of Reinforcing Bar Characteristics on Flexural Strength of Beams

Abstract

Reinforced concrete (RC) frame members under seismic loading are likely to experience large inelastic deformation, therefore, sufficient ductility Brittle mode enhancements must be avoided to enhance the potential for energy dissipation. These components are satisfied and satisfied after the earthquake. The event depends to a large extent on the nature of the materials used in its manufacture. That is, steel and concrete. This research is concerned with Strengthen steel in bending behavior until failure. When the capacity design for the reinforced concrete buildings or structures is sufficient real capacity does not exceed the actual design capabilities. In addition, RC member is a large inflexible deformation is expected to produce sufficient seismic dissipation. Because of the ability to bend. The post-productivity performance of RC members is mainly controlled by steel rods, which have some special characteristics. Performance requirements strength of yield, strength of tension and elasticity the steel manufacturing method. Thirty years of bending test Reinforced concrete beam was observed using carefully controlled steel bars. The reliable bending behavior and YS and UTS values must be within a narrow range around the value used design Members. If these values are greater than the specified value, they may cause a crisp cut failure instead of more bending and perfect bending failure modes.
