A composite primary steel beam with a span of 8m supports a secondary beam at midspan, which applies an characteristic (unfactored) load of 239kN to the primary beam. What elastic modulus (in cm³) does the beam require to be able to carry the load if the allowable stress due to the characteristic loads is 210N/mm2? It may be assumed that the elastic modulus required for the composite beam is 63% of that required for the equivalent non-composite beam.
