In structural engineering, both trusses and beams are essential components used to support loads and transfer them to the building's foundation. However, they differ in their design and application.

Truss:

A truss is a framework composed of members connected at joints to form a series of triangles.

Trusses are typically lightweight and designed to efficiently support loads over long spans.

They are commonly used in roof structures, bridges, and other structures requiring large clear spans.

Trusses are advantageous for their high strength-to-weight ratio and ability to distribute loads effectively.

Beam:

A beam is a horizontal or inclined structural member that supports loads by resisting bending.

Beams are usually solid or hollow in cross-section and can be made of various materials like wood, steel, or concrete.

They are often used in floor systems, bridges, and building frames to support loads and transfer them to columns or walls.

Beams are characterized by their stiffness and ability to resist bending and shear forces.
