The simply supported beam shown on figure Q2 is to be designedfor a central point load, P, made up of 90kN of dead load and 25kNof floor imposed load (the dead load value includes a conservativeallowance for the beam’s own self-weight). The supports and thelocation of the point load all provide lateral and torsionalsupport but do not restrain the flanges from rotation on-plan. Thebeam is to support brittle finishes. Choose a suitable S275Universal Beam, making full use of the Eurocode 3 member capacitiessection of P363, rather than calculating capacities by hand usingCode clauses, to satisfy both Ultimate and Serviceability LimitStates (ULS and SLS). The central deflection of such a beam, with acentral point load P is given by PL3/ 48EI. Please note that inthis question you are being examined on your ability to use thepink pages member capacities part of P363, and marks will not begiven for performing calculations by direct application of codeclauses instead.
