Critical Reviews on Design and Analysis of Stiffened Rectangular Hollow Cantilever Beam

Abstract

Hollow Cantilever beam are used widely in offshore, Bridges, steel structural and heavy duty machine normally used in cranes
like Telescopic boom crane. During the loading and unloading operation some concentrated load and self-weight applied on the
beam. This is produce bending and buckling moment and shear force in planes. Design engineers have great challenge to provide
the better robust design of beam which can withstand applied load with optimize design. From the literature survey strengthening
of beam or plate are provided by applying transvers or/and longitudinal stiffeners which can withstand post buckling and lateral
buckling moment. Thus, it is very much necessary for the designers to provide not only a better design of parts having maximum
reliability but also of minimum weight and cost, keeping design safe under all loading conditions. Presented paper focuses on
work done carried out by other researches in the same era, and found that number of stiffeners and its locations and its
dimensional property affect the behaviour of beam strength.
