NUMERICAL APPROACH TO THE INFLUENCE OF THE PROTECTIVE LAYER THICKNESS ON THE MECHANICAL PROPERTIES OF THE REINFORCED CONCRETE BEAM
In this paper, MFPA (Material Failure Process Analysis) is utilized to simulate the failure process of a reinforced concrete member under the condition of four-point bending. The influence of protective layer thickness on the mechanical properties of reinforced concrete beam is the main subject studied. The results indicate that an increase of the protective layer thickness will reduce the sectional effective height of the beam, which decreases the bearing capacity of the member. Therefore, choosing the protective layer thickness properly will yield the preferred properties in the member. In this study, it was found that a reasonable protective layer thickness is within 90 mm. However, it is necessary for the protective layer thickness to be confirmed by relevant specifications and standards on the premise above.
