Beam Sizing Checks For Residential Structural Design

Beam Sizing Checks

Beam sizing is an important part of residential structural design. Before selecting a beam, we review the span, loading conditions, support points, wall locations, roof loads, floor loads, and any point loads coming from above.

Load Review

We calculate dead loads, live loads, roof loads, floor loads, and tributary areas to understand how much weight the beam must carry. The loads are then converted into line loads or point loads based on the project conditions.

Structural Checks

After the loads are confirmed, the beam is checked for bending, shear, bearing, and deflection. We also review support reactions, post sizes, connection points, and whether the load can safely transfer to the foundation or existing structure.

Beam Options

Depending on the project, the beam may be designed as timber, LVL, glulam, steel, or flitch beam. The final member size depends on the span, load, depth limits, support conditions, and applicable building code requirements.
