The Effects of Building Elements and Smoke Layer on Fire Spread Between Combustible Materials

Report Date: January 2007

This project from Japan studies the fire spread characteristics between combustibles in a building compartment. These fire spread characteristics and smoke layer characteristics are investigated by varying the distance between the fire sources and the wall, ceiling height, and the depth of the wall suspended from the edge of the ceiling. This research seeks to validate numerical calculation methods for approximating fire spread through the live-fire experiments, and in doing so provides research-based insight into how building design elements and fire load can affect fire spread between combustible materials. It also provides a mathematical explanation of the characteristics of the smoke layer and the interaction between the flames and smoke layer as the fire grows.

  • International Association for Fire Safety Science

    IAFSS was founded with the primary objective of encouraging research into the science of preventing and mitigating the adverse effects of fires and of providing a forum for presenting the results of such research.The International Association for Fire Safety Science perceives its role to lie in the scientific bases for achieving progress in unsolved fire problems. It will seek cooperation with other organizations, be they concerned with application or with the sciences that are fundamental to our interests in fire. It will seek to promote high standards, to encourage and stimulate scientists to address fire problems, to provide the necessary scientific foundations and means to facilitate applications aimed at reducing life and property loss. Since its inaugural meeting, the IAFSS has grown to more than four hundred members. Current members come from Australia, Austria, Belgium, Brazil, Canada, China, Denmark, Germany, Finland, France, Holland, Hong Kong, India, Ireland, Italy, Japan, Korea, Luxembourg, Netherlands, New Zealand, Norway, Russia, Spain, Sweden, Switzerland, Taiwan, United Kingdom and United States of America. The Association is legally established as a charitable organization in England and Wales.

  • Takenaka Research and Development Institute

    Takenaka has the world’s largest state-of-the-art R&D Institute. Never before in history, have the issues been more challenging and finding solutions more crucial. Takenaka's planners, architects, engineers and contractors must meet ever more complex client needs with increasingly advanced technologies. But such technical innovation requires two things -- imagination and painstaking R&D.

    That's where the Takenaka Research and Development Institute comes in. We provide the answers.Takenaka is not just building buildings, we are building the future.

  • Kyoto University

    The current rapid changes of the social environment have brought about a need to develop studies on architecture as a synthetic system as well as the studies in fundamental and advanced fields, in order to produce higher quality and multi-functional living space. Thus, it is essential to promote the integration of many different fields.

    In the department, innovative methodologies and fundamental and advanced knowledge in related fields are lectured on and investigated.

  • Tokyo University of Science

    In 1981, Tokyo University of Science established Department of Fire Science and Technology in its Institute for Science and Technology. The aim was to set up a research center that would promote research on the safety technology to protect human life and property from fires, and research on the fire science that supports the technology. This development was initially started by the inauguration of a course on Architectural Fire Safety Engineering when the Department of Architecture.

    TUS was founded some 40 years ago. In this way, TUS laid the foundations of research and education on fire science ahead of the times, when such developments were unknown in other universities. These foundations have yielded a strong track record of achievements since then, as amply illustrated in the fact that we have received two prestigious awards from the International Association for Fire Safety Science, the highest authority body of its kind in the world. The first of these was awarded for "Meritorious achievements in research contributing to the advancement of fire safety science", and the second was for "Meritorious achievements in education producing numerous researchers in fire science". In the past, Japan has suffered many fires in large buildings, which have claimed a large number of human lives. Members of the Department of Fire Science and Technology, TUS have been involved in appraising the majority of these serious building fires since 1968.

    In recognition of this track record, the Department was included in the 21st CenturyCOE Program of the Ministry of Education, Culture, Sports, Science and Technology (MEXT) in fiscal 2003, as a“ Center of Advanced Fire Safety Science and Technology for Buildings”. It is currently engaged in activities aimed at establishing itself as a research and education center on fire science and fire safety engineering at the world’s highest level. Other aims are to promote the advancement of fire safety engineering and the training of young researchers and specialist professionals. We will continue our efforts in offering innovative education and research to protect human lives and properties from fires. Following the 21st Century COE Program, which concluded in 2007, the Global COE Program 2008, which would conclude in 2012, further adopted the "Center for Education and Research on Advanced Fire Safety Science and Technology in East Asia". Now, the Center restarted as a five-year project after having been selected as a 2013 recipient of the Private University Strategic Research Formation Assistance Grant from the MEXT.

    The aim of this program is to use the research results produced at our institution to contribute to reducing fire risks in Asia, and to protect the safety of the people who live in cities. The main content of this program can be divided into the following two themes.

  • General Building Research Corporation of Japan

    The General Building Research Corporation of Japan (GBRC) is a nonprofit foundation which was established in 1964. The mission of GBRC is to improve quality and safety of buildings for the public welfare by conducting wide-ranging research and testing activities in the building construction fields.
