Q3. Noting that a single steel 300PFC beam section appears to have adequate strength, now check if it would have adequate stiffness to limit the sag to L/300 over the 3.6m span when subject to a uniformly distributed SLS line load (for the mezzanine storage level), w, for G+Ψ_lQ, of w = 14.9kN/m. Analyse the beam as though it is simply supported over the 3.6m length (this is a conservative assumption) and assume that steel is not affected by creep. Report the ratio of the displacement demand to the displacement limit in %.
