Justify the selection of standard rolled steel sections for beams and columns to satisfy given specifications. 1. Beam Selection Select a standard rolled steel I-section for the simply supported beam shown in Figure. A factor of safety of 6 is to apply and the ultimate tensile strength of the material is 500 MPa. The selected section must have the least possible weight. The weight of the beam itself may be neglected when calculating the maximum bending moment 2. Column Selection A strut of length 8m with one end direction-fixed and one end pin-jointed is required to carry a compressive load of 750 kN. Select a suitable universal steel column that satisfy the given specifications and has the least mass.
