Structural beams are horizontal components that provide stability and support to buildings across various construction projects, from residential homes to highway overpasses. Made from durable materials like steel and concrete, these beams withstand diverse loads and forces while playing a critical role in foundation systems.

Connection to Underpinning

Structural beams are essential in underpinning — the process of strengthening and stabilizing existing foundations. Three primary underpinning methods utilize beams:

• Beam and Base Method: Constructs reinforced concrete beams below, above, or replacing existing footings to transfer building loads to concrete bases.
• Pier and Beam Method: Places reinforced concrete beams transferring loads to concrete bases or piers for added stability.
• Pile and Beam Method: Installs mini-piles alongside walls, particularly useful when access is limited or high load capacity is required.

Beam Classifications

• Steel Beams: Strong, durable rolled steel sections available in various shapes (I-beams, C-channels).
• Lattice Beams: Lightweight with high strength-to-weight ratio, ideal for long-span structures.
• Universal Beams (UB): Standardized I-beams used in frames, floors, and roofs.
• Fixed Beams: Restrained at both ends, capable of carrying substantial loads.
• Cantilever Beams: Supported at one end, extending outward for balconies and overhangs.

Foundation Role

Foundations support structural beams through weight distribution, load transfer, structural anchoring, level surface provision, and soil movement resistance. Different projects require different foundation types — spread footings for low-rise residential buildings and deep foundations for larger structures.
