Abstract
The fire behaviour of the Automated Rack-Supported Warehouses (ARSWs) is a topic of great interest for both the scientific community and the manufacturers of industrial racks. ARSWs are a particular type of steel racks that combine the structural efficiency of steel construction with automated machines for handling stored products. This work has addressed the fire modelling and structural thermo-mechanical assessment of Auto-mated Rack Supported Warehouses. The study is composed of two phases: the first one regards the investigation of the fire modelling which can be used in a multi-depth ARSW structure, by adopting localized fire models, zone models, and Computational Fluid Dynamics models. A fire model that allows vertical and horizontal propagation, starting from a localized fire, evaluated, and validated against experimental results available in the literature, is proposed. Also, a criterion to evaluate the vertical and horizontal propagation times is provided. The second part of the work focuses on the study of the structural collapse mechanism and on the methodologies of analysis that the designer should adopt to properly interpret it. Several thermo-mechanical analyses were carried out by using all the results of the proposed fire model and compared with different fire models available in the literature. To correctly analyse the progressive mechanism of collapse, an iterative procedure is proposed by using several subsequent implicit analyses carried out with SAFIR software, by comparing this one with an automatic procedure by using the software ABAQUS CAE which allows the implementation of implicit/explicit analyses.
