A steel beam having a span of 6.4m is simply supported at its ends and is laterally unrestrained over its whole length. It supports a uniformly distributed permanent action (dead load) (G) of 13 kN/m over its whole length, and a point load of 20 kN acting as an imposed action (live load) (Q) at midspan. wat RS Loading information: Load combinations: W= 1.2G+1.5Q Self-weight of the beam can be disregarded in all calculations (a) Sketch the load diagram on the diagram below that shows the loads on the beam for the load combination above, and calculate the design moment (maximum bending moment) and the design shear force (maximum shear force).
