ANALYTICAL METHOD FOR DESIGN OF FIRE RESISTANCE OF STEEL STRUCTURAL ELEMENTS
Full text linkThe engineering approach in the design of fire prevention allows the engineer to study fire pre-vention solutions that do not meet the requirements of the Rules provided that they ensure the same level of fire safety.
To design interventions appropriate to ensure the fire resistance of structures, and in particular for the steel structures, the performance approach of the Rules requires the adoption of prede-fined solutions as a function only of the structural material and the required fire resistance.
The performance approach of the Norms, therefore, does not take into account the loads acting on the structural element and the critical temperature, which is the temperature at which the load that can be worn in hot equals the exercise load.
Often, during the design phase, some of the requirements of rules are difficult, if not impossible to meet. A practical example is that of a restoration project of a historic building, for which interventions are required non-invasive, reversible and compatible.
In this paper it is presented a study that enables you to design interventions appropriate to en-sure the fire resistance of structural elements with an analytical method and, therefore, with an engineering approach. In particular, according to the fire scenario adopted, the analytical method proposed allows to determine the critical temperature of the structural element under study, depending on the working load, the resistant section and solicitation of project.
Subsequently, depending on the critical temperature and the required fire resistance, it is possible to design the appropriate fire-fighting interventions

The circular economy and consumer behaviour: The mediating role of information seeking in buying circular packaging
No full textThe transition towards a circular economy is a crucial issue to pursue a more sustainable development. In this transition, consumers' comprehension and engagement are necessary points to guide them towards more environmentally conscious purchases. This study extends the understanding of green consumer behaviour by testing an integrated conceptual model that explores the influence of personal concern, other pro-environmental behaviours, greenwashing beliefs, consumer innovativeness, and personal predisposition to seeking information on the purchasing of circular packaging. We explored both the stand-alone and the mediating effects of information seeking. Data were collected from a questionnaire-based survey administered to a large and representative sample of Italian families, using 1,643 valid responses. We used structural equation modelling to test the proposed hypotheses. The results highlight the fundamental importance of seeking information in order to guide consumption choices that are more consistent with the circular economy. For managers, our paper suggests that packaging counts in purchasing decisions and that information is used by consumers to search for consistency between personal attitudes, other pro-environmental behaviours, and the circular attributes of packaging
