EFFECT OF LOADING TYPE ON THE EFFECTIVE MOMENT OF INERTIA OF REINFORCED CONCRETE BEAMS

The deflection of cracked reinforced concrete beams tested under various types of loading is investigated and the effect of the type of loading on their effective moment of inertia is discussed. Four type of loading were considered in this study, which include: midspan and third-point concentrated loads, uniformly distributed load, and a combination of a midspan concentrated and uniformly distributed load. The value of the effective moment of inertia was found to be significantly affected by the type of loading used. Therefore, to account for such an effect, a newly developed model for estimating the effective moment of inertia of cracked reinforced concrete beams under any type of symmetrical loading is proposed.
