Fire safety in buildings usually relies on the withdrawal of smoke or the preservation of stratification to allow proper evacuation of occupants. In order to assess safety levels, much work has been done in the past, leading to regular prescribed solutions. However, in the case of large enclosures such as theatres or sports arenas, the degree of precision of these classical methods is not well known, leading to high calculated safety coefficients and thus high construction and operating costs. This paper is devoted to a specific project where smoke motion simulations were run to help conceive a more cost-effective design. After completion of the building, a large-scale fire test was performed inside to validate the conclusions of the numerical study. The paper focuses on this fire test and subsequent simulations performed on the fire test scenario and aims at comparing the numerical and large-scale experimental results. Several simplifying modelling hypotheses (geometry, fire modelling, boundary and initial conditions) are examined and compared with the test. Provided enough care is taken in the simulations, these results show that good agreement can be reached. Recommendations are drawn on this basis.
The international seminar for fire safety of facades (FSF) was created in 2013 to gather international experts in the field of fire safety for façade, to provide them the opportunity to present their work and research activities, to receive feedback from their colleagues and to establish collaborations and discussion with their peers. The 1 st international seminar for fire safety of facades was held in Paris 14-15 November 2013. In response to the call-for-paper we received about 50 excellent abstracts coming from the entire world and illustrating the importance of the subject of fire safety of facade in the international community. The scientific committee, composed of well-known researchers in the field of fire safety, selected 23 abstracts for possible oral presentations at the seminar and 23 for posters. These abstracts led to 38 papers published in these proceedings. They were grouped into the following topics: • Standardization and Regulations • Test and assessment methods • Fire safety engineering • Facade systems • Case studies • Products and material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
