Beams are essential structural elements that are used in construction to support loads across a span. They are designed to resist bending, shear, and deflection, and can be made from a variety of materials, including steel, timber, concrete, and composites. Beams are typically planar, but can also be curved or tapered, depending on the specific application and design requirements. One important aspect of beams is their cross-sectional shape, which can significantly impact their strength and stiffness. Common cross-sectional shapes for beams include rectangular, circular, I-shaped, and T-shaped. The choice of cross-sectional shape will depend on the specific requirements of the application, such as the magnitude and direction of the loads, the span length, and the available materials. Another key aspect of beams is their ability to transfer loads through internal forces, such as bending, compression, and tension. The design of a beam must take into account the expected loading conditions, including the magnitude and direction of the loads, as well as any dynamic or environmental factors that may impact the structure over time. In addition to their structural properties, beams can also have aesthetic and architectural significance, particularly in building design. For example, exposed timber beams can add warmth and character to a space, while steel or concrete beams can create a modern, industrial look. Overall, beams are a critical component of many construction projects, providing essential support and stability to structures of all types and sizes.

Beams are structural elements that carry loads across a span and are commonly used in construction. They are typically made from steel or timber, but can also be formed from composites, masonry, and reinforced concrete. Beams are usually planar, but can also be curved or tapered. They are categorized according to their cross-sectional shape, spanning capability, strength, and stiffness. For example, a cantilever beam is able to support a load without the support of an external force, while a truss beam relies on internal force transfer for stiffness and strength. Depending on the beam's configuration, different loading cases can be used, such as pure bending, axial loading, torsion, and shear loading. Additionally, beams can be statically or dynamically loaded.
