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

  1. Rankine formula
  2. Marcus formula
  3. Rankine Grashoff formula
  4. Grashoff formula

Answer: C.  Rankine Grashoff formula

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.

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.
