The beam shown is a two-span beam with a hinge in the center of the left span. There is continuous lateral support. The concentrated loads are service loads. Determine whether a W12x79 of A992 steel is adequate. Use LRFD. Don’t forget to include self-weight. Please draw the complete shear diagram for the beam

Question 4: Select an appropriate W310 section of ASTM A992 steel (F, = 345 MPa) as the beam-column in an unbraced frame subjected to the factored loads, including biaxial bending moments, as shown in Fig. 4. The beam-column is laterally braced at the two ends only. (Hint: I would start with W310x118 and then decide if this is an appropriate choice or a heavier/lighter section is necessary depending on the outcome of checking interaction equations.) 1040 kN 1040 kN 125 kNm 85 kNm W310 W310 7000 %3D II 235 kNm 50 kNm 1040 kN 1040 kN Figure 4
