ABSTRACT:
A cantilevered structure comprises two cantilevers of unequal length adapted to span a gap (L) and overlap at their free ends so that load transfer may take place from the longer to the shorter cantilever. The cantilevers have the same Youngs Modulus, cross-sectional shape and same load per unit length applied to them, and the line of action of the load transfer between the cantilevers is up to 34% of the distance (L) between their encastres. The sum of the leading moments at the encastres of such cantilevers is lower than is the case with overlapping cantilevers where the line of action of load transfer between them is more than 34% of the distance between their encastres.
