What is Allowable Deflection ? – Trus Joist Technical Support

What is Allowable Deflection ? Deflection is the bending or "sag" caused by loading. Allowable deflection is generally expressed as a fraction of the span, in inches. All structural members will deflect or flex under load. The amount of flex depends on the magnitude of the load applied, span of the member, and stiffness of the member.
