A Universal Beam UB in grade S275 steel (B/1-2-3) is shown in Figure Q2 over a span of 9.0 m. The beam is laterally restrained at B1, B2, B3 and B4 but unrestrained between these points. The depth of the beam must not exceed 425 mm, and the ceiling under the beam will be plastered. You are required to design and select a suitable UB section, based on the following criteria: (a) Bending in ULS (b) Shear in ULS (c) Deflection in SLS 3.0 m B G-3.33 kN/m2 Q-5.22 kN/m² 3.0 3.0m PB2 PLAN VIEW Figure Q2 Pas G-2.55kN ² Q-3.11 kN/m² 3.0 (Total: 50 marks) (20 marks) (20 marks) (10 marks) UDL. -13 IN A Universal Beam UB in grade S275 steel (B/1-2-3) is shown in Figure Q2 over a span of 9.0 m.
