Floor deflection

Significant floor deflection

Deflection in engineering is the movement of a beam or board from its original location. Some refer to deflection in engineering as displacement. This refers to the movement that comes from engineering forces, either from the item itself or from an external source, such as the weight of the walls or roof or loads on top of it. Most structures are at risk of deflection, including floors, beams, frames, and even columns.
Deflection is a critical consideration in structural engineering, as excessive deflection can lead to structural failure, reduced functionality, and compromised safety. More information in the featured article < stability >

Deflection is a phenomenon that is mainly caused by 3 factors, viz;
1. Too thin flooring boards or too small beams 
2. The distance between the supporting joists is too large
3. The type of material 

In engineering, there are special dedicated codes that determine the maximum allowable deflection in structures. Our structures comply with these codes, either for floors, beams, or columns.
