【摘要】 建筑的性能化防火设计方法是目前国外消防科学研究中发展最快的一个前沿的热门研究领域，它建立在消防安全工程学的理论和相关应用技术基础上，是消防安全工程技术发展的必然趋势与结果。随着建筑工业的快速发展，这一全新的设计理念逐步引入国内，而国内消防工程设计人员及审核人员设计审核水平参差不齐，为了规范设计审核人员的行为，有必要及时开展适于我国国情的性能化设计指南的编制工作及辅助设计、分析工具的适用性验证工作。本文在分析国内外性能化防火设计方法的基础上，尝试提出在我国开展性能化防火设计工作的模式。论述了目前性能化设计过程中场模拟软件的使用情况，提出了场模拟软件适用性问题，并针对这一问题提出了评价其适用性的方案。论文的主要内容包括：1．分析了国内外性能化防火设计方法和发展现状，提出了本文开展性能化防火设计的模式。2．运用灰色综合评价方法确定了建筑火灾危险性与人员安全疏散程度间的关系。3利用BP神经网络方法，提出建立建筑火灾危险性与人员安全疏散程度间的关系模型化的方法，并使用MATLAB数值分析软件中神经网络工具箱将建筑火灾危险性与人员安全疏散程度间的关系模型化。4．针对具体的建筑实例，使用FDS火灾模拟软件对其进行了模拟，并运用所建立的建筑火灾危险性与人员安全疏散关系模型，对建筑人员安全疏散情况进行了分析，由结果对比分析，对场模拟软件适用性进行了验证。更多还原

【Abstract】 Building performance-based fire protection design is the most pop and fastest developed research field in overseas fire science research, it is based on the theory of fire safety and related applied techniques, and it is the inevitable current and subsequence of developing of fire safety technology. Along with the fast development of construction industry, the PBD method comes into China, but the fire safety engineers and the Authority Having Jurisdiction have different capability, in order to unify the design and auditing action, it is necessary for us to do the work of compiling engineering guide to performance-based fire protection analysis and design of buildings and validating the availability of analysis tools.Based on the performance-based design method of other countries, this paper try to bring forward the details of performance-based design method. It discussed the usage and availability issue of the field simulation software, and prompts the solution. The main content of the paper include:1. Analyzed the performance-based design method and its now situation in other countries, brought forward the details of performance-based design method.2. Found the relations between building fire hazard and occupant evacuation using the gray synthetic assessment.3. Use the BP neural network, established the method to model the relations between building fire hazard and occupant evacuation, modeled the relation using MATLAB4. The author simulated the example using Fire Dynamic Simulator and analyzed the occupants evacuation in the building using the established model, validated the availability of the field simulation software comparing the outcomes.更多还原
