Determine the ultimate moment capacity of the beam with given properties below. d' = 70mm d = 430mm b = 370mm fc' = 30MPa fy = 315MPa As = 5-32mm bars a. USE NSCP 2001, Mu = kN-m b. USE NSCP 2015, Mu = kN-m

Two structural steel angles back to back are used as a compression member that is 4.5 m long. The angles are separated at intervals by spacer blocks and connected by bolts as shown in Figure Q4, a configuration which ensures that the double-angle shape acts as a unified structural member. Assume the pinned connections at each end of the column, and use E=200 GPa for the steel. A single angle has the following properties, A = 1600 mm, Ix = 1.64 x 106 mm4, Iy =0.787 x 106 mm4, x = 19.7. Determine the Euler buckling load for the double-angle column if the spacer block thickness is 5 mm (10 marks) 20 mm (10 marks)
