For a 7 m tall column (pin ended in a braced structure) that supports an un-factored dead load of 350 kN and un-factored live load of 200 kN. Column's dimensions: 500 mm 500 mm, f'c = 24 MPa, fy = 420 MPa. The bending moment diagram for the column is shown below. Consider the following; Bd = 0.5676 Find only, the critical moment (M) and load (P) to be used in the design of this column. Don't use the sheets of interaction diagrams = MD 40 kN.m ML 40 kN.m MD 10 kN.m = ML 10 kN.m =
