Cantilever beam refers to a beam that is fixed at one end and free at the other, making it a key structural element used in construction and engineering. This type of beam is designed to carry loads along its span while relying on the fixed end to resist bending moments and shear forces. The cantilever beam is widely used in structures such as balconies, bridges, overhangs, and roof projections, where intermediate supports are impractical or aesthetically undesirable. Its ability to project horizontally or at an angle without external support on the free end makes it particularly useful in modern architectural designs. Cantilever beams experience maximum bending moments and deflections at the fixed support, which must be carefully analyzed to ensure stability and safety. Materials such as steel, reinforced concrete, and wood are commonly used in their construction, depending on the required load-carrying capacity and span. Engineers must consider factors such as load distribution, deflection limits, and material strength when designing cantilever beams. This type of beam is especially valuable in creating open spaces or bold architectural features, as it eliminates the need for columns or additional supports. Proper design and analysis of cantilever beams allow for efficient and innovative structural solutions.
