A beam is a structural element that I mainly resist loads, applied alongside to the beam's axis. Its mode of deflection I is mainly by bending. The loads applied to the beam I result in reaction forces at the beam's maintenance points. The total effect of all the forces acting on I the beam is to produce shear forces and bending moments within the beam that in turn make internal stresses strains I and deflections of the beam. Beams are categorized I by their method of support summary shape of cross-section length and their material. Beams are categorized as the following types according to end support. Simply Supported Beam, Continuous Beams, Overhanging Beams, Cantilever Beams, Fixed beams. Simply Supported Beam Simply supported beam is I supported at both ends. One end of the beam is maintained by axis support and other one by roller support. This support allows to horizontal measure of beam. Its beam-type suffers I both shear stress and bending moment. Continuous Beams. This beam is like to simply supported beam. One end of it is supported by hinged support and the other one is I roller support. One or more supports are used between these beams. It is used in long actual I bridge where the length of bridge is too large. Overhanging Beams Overhanging beam is a mixture of the simply supported beam and cantilever beam One or both of end overhang of this beam. This beam I is maintained by roller support between two ends. This type of beam has inheritance belongings of the cantilever and I simply supported beam.
