Fire modelling and structural assessment of automated clad‐rack warehouses

Abstract Automated Rack Supported Warehouses (ARSW) are self‐bearing rack structures designed to support, besides self‐weight and weight of products, environmental loads (i.e., wind, snow seismic action) all the other non‐structural elements. These unique in design; indeed, they represent a topic great interest for both scientific community manufacturers industrial racks. However, behavior case fire these is still poorly known. In order study resistance consider natural curve necessary. particular, vertically traveling model upright frames, starting from localized has be modelled. This paper proposes that considered vertical horizontal propagation, evaluated validated against experimental test results. addition, advanced thermo‐mechanical analyses using nominal curves, were performed with finite element software (SAFIR), which allows modeling Class 4 steel elements considering local instabilities can occur slender sections. A comparison between capacity models regulations propose structural elements, was also conducted.
