Optimizing the construction elements of underground parking through temperature distribution analysis in fire situations

摘要

Since the early twentieth century, specialists have conducted experiments over various types of buildings in order to analyse their behaviour during fires. Initially, first tests were carried out on real size models. Over time, these tests became difficult, even impossible, because of increasing complexity of buildings. The explosive evolution of Computer Science field has allowed the development of new software - tools for simulation of fire process, generally and also for buildings. At the beginning of 2000, NIST (National Institute of Standards and Technology - USA) in partnership with some public and private organization from USA and Europe has released an ,,open source" software, called Fire Dynamics Simulator (FDS), in order to build a computational fluid dynamics (CFD) model of fire-driven fluid flow (heat, smoke emission, hot gases etc.). This work paper presents a FDS fire simulation for a building with multiple functionalities/purposes, such as parking, administrative and/or civilian buildings. Also, this paper presents the observations based on the analysis of fire expansion in different scenarios.
