studied flat slab models

The selected six flat slab models having irregular columns layout is shown in figure-2 (a to f) . The concrete compressive strength\(\mathbf{(f}_{\mathbf{c}}^{\mathbf{{}^{\prime}}})\) and the steel yield strength\(\left(\mathbf{f}_{\mathbf{y}}\right)\) for these slabs are 30 MPa and 400 MPa respectively. The columns presented in the flat slab models are having the dimensions of (500 mm x 500 mm). Also, the elastic modulus of steel (E) and the density of concrete (\(\gamma_{c})\ \)used in this study are \(200,000\ MPa\) and\(25\ kN/m^{3}\).
