Q2. An isotropic rectangular slab (6 x 8) m is fixed at 3- edges and free at one edge as
shown below. The reinforcement provides a positive yield moment of (10) kN.m/m
and along the fixed edge a negative yield moment (m) of (14) kN.m/ m.
Determine the collapse load if the slab carries a u.d.L. of (w) kN/m² including the
slab own weight.
