How does span length between supporting walls or columns affect roof slab thickness?

Longer spans between supports generally require a thicker slab or additional reinforcement to safely carry load and control deflection, which is why the calculator asks for span information rather than assuming a fixed thickness regardless of room size. Your structural engineer's design should be the final authority on slab thickness for any span beyond a […]

Longer spans between supports generally require a thicker slab or additional reinforcement to safely carry load and control deflection, which is why the calculator asks for span information rather than assuming a fixed thickness regardless of room size. Your structural engineer's design should be the final authority on slab thickness for any span beyond a standard room size.
