Design and Analysis of Reinforced Concrete Flat Slab Using Various Codes

Abstract

The slab is typically supported by a beam, and the beam, in turn, is supported by a column in the standard design and construction method. The term "beam column construction" refers to this kind of building structure. However, in the case of the flat slab design, we are erected without the use of beams, which means that the available net clear ceiling height of the structure is not diminished. When compared to a conventional slab, which is a slab that rests on beams and columns in a frame building, the formwork for a flat slab construction is much simpler. Additionally, the reinforcing scheme is also much simpler, and the storey height is reduced. Check for the second order effect in flat slab buildings (the second order effect is also known as the P-Delta effect). limitations have been placed on the P-Delta ratio in today's international design standards. These limitations appear to have been established to maintain a minimum reloading stiffness during cyclic response and with adequate regard for the expected ductility demands put on structures. It has been proposed that the present code limitations should be reviewed for tall buildings due to the limited displacements that genuine earthquake ground movements impose on such buildings.
