| Summary: | Due to the recent fire events in open car parks and in order to increase the fire safety in this type of the building structures, simple calculation methods should be developed to estimate the thermal effects of a localized fire. This investigation deals with a parametric analysis, using different fire events (different vehicle classes), fire scenarios (relative position of the car with respect to the main element of the structure and dimensions of the compartment) and section factor of the main supporting element of the structure (dimensions of the beam cross section). The temperature was calculated for each fire scenario, around the beam (gas temperature) and also in the steel beam. The thermal effect on part of the structure was calculated by a mixed formulation, taking into consideration the Hasemi and Heskestad methods to evaluate the temperature of the gas and also the lumped thermal model for the calculation of the steel temperature. These results will be compared with the results obtained using the software Elefir-EN and CFD simulation by Ansys FLUENT.
