Question 1A (TOTAL 25 MARKS) The continuous beam shown in Figure 1A is constructed using a single hot-rolled I section 360UB50.7. The properties of the section are shown in Table 1A Table 1A Dimension and properties of 360UB50.7 d 356 mm Ix 142x105 mm Sy 173x10³3 mm³ 3 be 171 mm Zx 798x10³ mm Ty 38.5 mm tf 11.5 mm Sx 897x10³ mm J 241x10³ mm¹ tw 7.3 mm Ix 148 mm Iw 284x10⁰ mm ri 11.4 mm ly 9.6x106 mm fyf 300 MPa d₁ 333 mm Zy 112x10³ mm³ fyw 320 MPa Ag 6470 mm² The point loads on the beam, P, consists of a concentrated permanent load (G) of 100 kN (including allowance of self-weight) and a concentrated live load (Q) of 200 kN. The UDL on the beam, W, consist of a uniformly distributed self-weight of 30 kN/m and a uniformly distributed live load 24 kN/m. The beam is bent about the major axis and has full lateral restraint. Show, using plastic analysis that the section is either suitable or unsuitable to carry the applied loads. KN W kN/m 4m- 2m-2m- 4m- b₁ Figure 1A d₁
