Effects of variations in loading and material properties on span: depth ratios for composite beams

A convenient way of satisfying deflection criteria for composite steel concrete beams is through the use of allowable span: depth ratios. In the methods presently available for determining allowable span: depth ratios, assumptions have been made regarding the value of some of the loading and material properties which affect the deflection of composite beams. A series of graphs are presented to show the effect on allowable span: depth ratios caused by changes to the value of the loading and material properties. The graphs show that for most cases the variations of loading and material properties are unlikely to produce large errors in span: depth ratios. A comparison with typical reinforced concrete beams indicates that, especially for reinforced concrete beams with no compression reinforcement, the changes to span: depth ratios for composite beams are less significant than those for reinforced concrete.
