Frequently Asked Questions

What is beam deflection?

Beam deflection is the displacement of a beam from its original position due to applied loads. It's a crucial factor in structural engineering to ensure beams don't deflect beyond acceptable limits.

What are the common beam support types?

Common support types include simply supported (pinned at one end, roller at other), cantilever (fixed at one end), and fixed-fixed (both ends rigidly fixed). Each has different deflection characteristics.

How does material affect beam deflection?

Material properties like Young's modulus (E) and moment of inertia (I) directly affect deflection. Higher E and I values result in less deflection under the same load.

What is the maximum allowable deflection?

Maximum allowable deflection typically ranges from L/360 to L/600 for most building codes, where L is the span length. This ensures structural integrity and prevents damage to finishes.
