Maximum Deflection
Span / 180 |
|||||
This table may also be used for wind uplift to a maximum of 0.4kPa with suitable lateral restraints. Where wind load governs, ie., in excess of 0.4kPa, the span shall be reduced. No provision has been made for the 1.3kN concentrated load. Where joist ends have rigid connections or are over multiple supports that spans may be increased. Consult your/our engineer for details.
