Composite roo? flight testing Client Hambeside Danelaw Project OFS measurement of dynamic loading and long-term residual strain build-up in GRP roof light to heath and safety executive requirements Resolution SmartPatch sensors were attached to the underside of the structure. Data were collected as 45kg sandbag drops were made from a height of 1.2m (the health and safety executive requirement). Dynamic data showed the maximum strain applied to the structure, and long term measurements showed that residual strain was built-up in the component as a result of successive bag drops.
