A conventional warehouse construction involves steel portal frames, lightweight metal roofing, and precast concrete panels or reinforced blockwalls in the elevations. Variations to this structural makeup include cantilever columns in the endwalls supporting concrete wall panels. Typically mezzanine office areas consist of timber or steel framing construction with timber flooring.
Common methods of strengthening warehouses involve:
Installing knee-braces between purlins and rafters
Additional connections between steel columns and precast concrete panels
Upgrading roof bracing and struts
Additional walers and strongbacks to precast concrete panels or blockwalls
Improving connections between mezzanine floors and the main warehouse structure
