The beam in Figure 2 is loaded such that it bends about the major axis. Use plastic analysis and design to check the adequacy of the beam given that the point load, P consists of 40kN of imposed load and 30kN of permanent load including self weight. The beam is made up of a grade 300PLUS, 310UC158 section with the following properties: d=327mm, be311mm, t25.0mm, tw-15.7mm, f 280MPa, fyw =300MPa, Ix-388x105mm, Zx-2370x10mm, S-2680x10mm, I-125x105mm, Z,-807x10mm, Sy-1230x10mm, Assume that the beam has full lateral restraint. 3P 2P P 3m 2m 3m Figure 2 2m
