Steel beam supporting Hollowcore slab design (EN1993)

New calculation which checks the design of a single span, simply supported, rolled I or H, ASB or Slimflor beam at multiple stages of the construction phase. In accordance with EN1993 and the national annex for the UK, Ireland, Singapore, Malaysia, Finland, Sweden, Norway or the recommended Eurocode values.
