This Architectural drawing is Typical Reinforced Concrete and simple beam with cantilever. Irrespective of the type of load, it bends downwards by creating a convexity upwards. This bending creates tension in the upper fiber and compression in the lower fibers. Hence main reinforcement is provided to the upper fiber of the concrete beam, as there is high tensile stress. Cantilever: A projecting beam fixed only at one end, while the other end has no support. Below we will analyze some classic loading examples of these beam categories. Simple Beam. The simple beam above has two supports and a center load. The simple beam has two supports at each end. For more details and information download the drawing file.
