Introduction

A beam is a structural member which carried load. These loads are most often perpendicular to its longitudinal axis, but they can be varying types. A beam supporting any load develops internal stresses to resist applied loads. The types of beam is determined by the kind of support the beam has at its ends or anywhere along its length. This is because each type of support generates of specific kind and combination of reactions.
Types of beam

A. Cantilever beam

Used to create the floating or hovering effect. This is used to create of a bay window, balconies, and some bridges. The weight load is spread back to the main beams of the structure in the cantilever beams and allowing a portion of the structure to go beyond the supported perimeters of the structure foundation. Building in downtown area Cincinnati. Overhang in building is supported on variable depth cantilevers. Loading on the cantilevers primarily tip loading due to outside columns. (Cincinnati, Ohio)

Entrance to stadium taken during construction. Roofing supported on variable depth glue-laminated cantilevers. Loading due to roof weight, wind, and snow. (Berne, Switzerland)

World Trade Center. Further example of building overhang supported on variable depth cantilevers. Note that adjacent cantilevers have common tip displacement. (New York City)

B. Steel I beam

B. Steel I Beam

Very popular choice in the construction is no other than steel I-Beam. The I-Beam is also known as W shape. This is widely used in the steel construction. This I-Beam design is common fundamental beam design in commercial structures, but it can be used in the residential design also. Continuous steel plate...
