Q2 Figure Q2 shows a braced frame structure of a laboratory building. The connection between column is fixed at top and bottom. Bending moments for column B are My = 15 kNm (top) and 20 kNm (bottom) at negative and positive side respectively. Use concrete strength, fck = 25 N/mm². (a) Calculate the design ultimate axial load for column B. Assume 4.5 m for beam span on z-direction to support the following floor loads. (6 marks) (b) Classify column B either short or slender based on BS EN1992-1-1:2004. (14 marks) (c) Calculate the possible design bending moment for column B by considering given My for both sides.
