ADVANCED MODEL FOR THE EFFECTIVE MOMENT OF INERTIA TAKING INTO ACCOUNT SHEAR DEFORMATIONS EFFECT

Authors

Abstract
The study aims to present anew form of the effective moment of inertia by enhancement Branson's model to take the effect of several factors such load type(concentrated, uniformly distribution, and two points) loads, shear deformations affect are also considered. These deformations depend on the span to depth ratio. The results of the presented model were compared with (experimental results, Branson's model results, and results of other models). The results of the present model give best agreement with experimental results than Branson's and the other models; the results showed that the effective moment of inertia reduced by about 27% for span to depth ratio of (20 to 5) due to shear deformation effects.
