Abstract
Flat slabs are highly versatile elements widely used in construction, providing minimum depth, fast construction and allowing flexible column grids. Common practice of design and In the present study, a hyperbolic shear deformation theory is developed for static flexural analysis of thick isotropic beams. The theory assumes a parabolic variation of transverse shear stress across the thickness of the beams. Simply supported thick isotropic beams analysed for the axial displacement, Transverse displacement, Axial bending stress and transverse shear stress. In this theory the hyperbolic sine and cosine function is used in the displacement field to represent the shear deformation effect and satisfy the zero transverse shear stress condition at top and bottom surface of the beams. The Governing differential equation and boundary conditions of the theory are obtained by using Principle of virtual work. The simply supported isotropic beam subjected to varying load is examined using present theory. The numerical results have been computed for various lengths to thickness ratios of the beams and the results obtained are compared with those of Elementary, Timoshenko, Trigonometric and other higher order refined theories and with the available solution in the literature.
