Comparative Study Of Conventional Slab, Flat Slab And Grid Slab Using ETABS
IOP Conference Series: Materials Science and Engineering, 2021 Abstract In today’s construction, the traditional slab is mostly supported by a beam, with a small slab thickness and a large beam depth, and the weight is carried from beam to column. The flat slab allows architects to place partition walls wherever they are needed. It is widely used because it reduces weight, speeds up building, and is

Analysis of Post-Tensioned Flat Slabs, Conventional Slabs, and Flat Slabs using Etabs Software
International Journal for Research in Applied Science and Engineering TechnologyAbstract: The modern-day submit-tensioning method is especially well-known because of its practicality; so, we will design the maximum safe and economical construction using this method. Every time we are planning the application of this technique, we must include more protective measures for slabs' shear and deflection criteria.
