Solution

Design of a two way slab simply supported on edges and having no provision to prevent the corner from lifting is made by Rankine Grashoff formula.

• Rankine Grashoff method, the effect of restraint against the lifting of the corner and the effect of torsion in slab is neglected.
• Marcus formula has given an approximate method for determining Bending moment in slab,simply supported on four edges with corner prevented from being lifted and considering the torsion in slab.
