The National Fire Protection Association (NFPA) periodically updates each fire safety code and standard that it develops. Acknowledging the need for a document to prescribe fire safety for historic buildings, a complete and thorough rewrite of NFPA 914 was undertaken. The former recommended practice has now been issued as the Code for Fire Protection in Historic Structures. The 2001 edition identifies a process for analyzing fire safety needs in historic buildings, outlines generic approaches to dealing with specific provisions of other codes that may endanger historic integrity, and includes a performance-based approach to fire safety in historic buildings. This paper describes the background, revision process, and current proposed content NFPA 914. 相似文献

The nature of historic buildings is considered from a firesafety viewpoint and some of the concepts of acceptable risk are described. The main approaches to the provision of adequate firesafety are discussed and the use of conventional fire precautions is reviewed briefly in the context of historic buildings.This paper is a revised version of a paper given at a seminar, Preventing Fire in Historic and Older Properties, organized by the Royal Incorporation of Architects in Scotland on April 19, 1988 at Hopetoun House, near Edinburgh. 相似文献

The Development of a Fire Safety Evaluation Procedure for the Property Protection of Parish Churches
Alexander G. Copping 《Fire Technology》2002,38(4):319-334
Incidences of fires in churches are currently exceeding those in all other historic building types. This trend is destroying irreplaceable national treasures as England and Wales contains one of the greatest collections, in terms of number and antiquity, of ancient parish churches in the world. This paper describes the development of a decision making tool to aid the custodians of parish churches in evaluating the existing fire safety provision and in gauging the cost of upgrading fire safety for property protection exclusively. The principles behind the evaluation procedure are detailed and the mechanics of assessment demonstrated. The tool, referred to as Fire(SEPC) [Fire Safety Evaluation Procedure for the Property Protection of Parish Churches] is unique in its evaluation configuration in that an acceptable level of fire safety is dependent on the vulnerability of the fabric and contents of individual churches. 相似文献

The International FORUM of Fire Research Directors (FORUM) periodically takes a position on a technical issue of international significance confronting the fire safety research community. The position of the FORUM on performance-based regulations, codes and design for fire safety applications, and the rationale leading to it, is described in this paper. Aspects addressed include current capabilities and challenges associated with the application of performance-based design, and possible enhancements (obtained through a coordinated and sustained global effort of research) in next generation tools leading to more certain predictions of the effects on performance of changes in building materials, active and passive fire protection systems, compartmentation, and egress systems; the structural response of a building to large fires including those leading to full building burnout; the impact of fire on neighboring buildings and infrastructure; and the uncertainty in deterministic predictions for incorporation into reliable probabilistic calculations of hazard and risk. 相似文献

当前,建筑防火设计规范向性能化方向发展。性能化防火设计所做的主要工作是火灾风险评估,而火灾场景设计是火灾风险评估的基础。以火灾荷载调查数据为基础进行典型商业建筑火灾场景设计的试验研究,设计大型购物中心内快餐店和运动休闲店两类店铺的燃料包并进行ISO 9705实体房间火试验,用于确定燃料包的燃烧特性,如热释放速率、毒性气体产生速率等。试验结果表明:快餐店和运动休闲店两个燃料包的火灾增长率处于中速火和快速火之间,并且偏向于快速火,两个试验的热释放速率的峰值都达到1MW左右,平均热释放速率快餐店为139kW,运动休闲店为191kW。试验结果可以为建筑设计师和消防工程师在火灾风险评估中设计火灾场景提供参考。 相似文献

Fire Safety Performance of Japanese Traditional Wood/Soil Walls and Implications for the Restoration of Historic Buildings in Urban Districts 总被引:2,自引:0,他引:2
Yuji Hasemi Noboru Yasui Michitaka Akizuki Koichi Kinoshita Koichi Yamamoto Masatomo Yoshida Yoshihide Tamura Mariko Takeda 《Fire Technology》2002,38(4):391-402
Grass-root research activities to clarify fire safety performance of Japanese traditional wooden construction are introduced. The activities aim to resolve conflict between the restoration of historic buildings and the reduction of risk and hazard of urban fires. Among various activities, scope and results of fire resistance tests on traditional soil wall assemblies supported by timber frame are reported in detail. The test results indicate an encouraging prospect for the rational fire safety assessment of historic buildings and further development of fire-safe traditional constructions for the restoration of historic buildings and historic urban districts. 相似文献

加拿大卡尔顿大学开发了火灾风险计算机模型CUrisk,用以评估四层木结构商品建筑的火灾安全设计。该模型包括系统模型和许多子模型。系统模型用于设定风险分析框架及控制子模型数据流。它还负责计算每个火灾场景的生命危险值。其他子模型包括火灾增长、烟气运动、边界失效火灾蔓延、人员反应和疏散以及建筑造价和经济损失等模型。利用子模型的输出数据,系统模型可计算三个决策参数:对生命的预期风险、对受伤情况的预期风险以及消防成本预期。这些参数是以可能的火灾场景及相关概率为基础的。文章简要介绍了CUrisk模型,并介绍了运用该模型对四层商业建筑所进行的多火灾场景风险分析的结果。 相似文献

目前,高层建筑的火灾防控难题一直未得到有效解决。针对高层民用建筑防火能力风险评估中评估指标获取不科学、指标体系差异大的问题,运用典型火灾事件分析法,结合《建筑设计防火规范》,科学获取影响高层建筑防火能力的12个主要不确定性风险因素,构建了更为科学的高层建筑防火能力风险评估指标体系。在此基础上,引入未确知聚类理论,构建了基于未确知聚类的高层建筑防火能力风险评估模型。并以8栋典型高层民用建筑火灾风险数据为例,进行实证分析。研究成果表明,该风险评估系统可行有效。研究成果可为高层民用建筑火灾风险防控提供一种新的方法和途径。 相似文献
