In engineering and physics, beams can refer to different types depending on the context. A classification is based on their support conditions: fixed beams are anchored at both ends, cantilever beams are fixed at one end and free at the other, simply supported beams are supported at both ends without resistance at any one time, and the continuous beams are supported at more than two points along their length, providing varying degrees of support and flexibility depending on the application.
Beams are structural elements that carry loads primarily by resisting bending.
In civil engineering, beams are crucial components in buildings, bridges and other infrastructure. They are designed to support vertical loads such as the weight of the structure itself and any applied loads such as people, furniture, vehicles or machinery. Civil engineering beams can be made from materials such as steel, reinforced concrete or wood, and they play a vital role in safely distributing loads to the foundation or supporting structures.
In reinforced concrete construction, beams are classified based on their cross-sectional shape and method of reinforcement.
Common types of reinforced concrete beams (RCC) include rectangular beams, T-beams (which have a T-shaped cross-section), L-beams (which have an L-shaped cross-section), and inverted T-beams (which Each type of RCC beam is designed to resist the bending and shear forces specific to its structural application, whether in buildings, bridges or other infrastructure projects.
Concrete beams can vary in their construction and purpose.
In addition to reinforced concrete beams used in structural applications, other types include precast concrete beams, which are manufactured off-site and transported to construction sites ready for installation. Prestressed concrete beams are another type, where internal stresses are intentionally induced to improve the loading capacity of the beam and reduce deflections under load. Concrete beams are versatile and widely used in construction for their durability, strength and adaptability to different architectural and technical requirements
