400 mm web angle connection web angle connection 4000 mm 4000 mm In a residential building, a W310x52 section of ASTM A992 steel (Fy-345 MPa) is selected to support a point dead load of 20 kN at its mid-span and a uniformly distributed live load of 1.5 kN/m. The beam is simply supported with a span length of 8000 mm. Include the beam self-weight in calculations. Use the load combination of 1.25 DL+ 1.5 LL. The beam is laterally supported only at the ends (supports). Members of floor are not susceptible to cracking. Use E- 200,000 MPa and G-77,000 MPa.
