Hiii guys..
i am running a rc slab subjected to fire in its tension side and then applying load on column.
the problem is that the deformation of slab is large so slab does not damaged
i defined specific heat, conductivity, density, modulus of elasticity and plasticity damaged for concrete
and the same but with plastic behavior for steel.
could anyone help me to see why this is happening.
i have attached the deformed shape of the model.
thank you..
