由ASCE结构工程研究所消防委员会编制。结构消防工程为基于性能的结构消防工程设计领域提供了最佳实践。当结构系统被火加热时，它们会经历传统结构工程设计所没有考虑到的热效应。传统上，在针对环境设计荷载（如重力、风和地震等）进行优化后，结构防火规定适用于结构。 这一具有百年历史的规定性框架致力于减少单个结构部件的加热，以降低火灾下结构失效的风险。因此，建筑物在不受控制的火灾中遭受结构破坏的脆弱性在不同的管辖区有所不同——这些管辖区对环境荷载有不同的结构设计要求——并且是建筑系统和组件配置的函数。作为替代方法，ASCE标准7-16允许应用性能- 基于结构防火设计（也称为结构防火工程设计），以类似于结构工程实践中处理其他设计荷载的方式，明确评估结构系统在火灾暴露下的性能。结构消防工程设计是根据特定的性能标准，对结构进行计算设计，以承受火灾的热荷载效应，其有可能改变结构的完整性。本手册MOP 138介绍了当前的实践、热分析和结构分析方法，以及支持结构消防工程设计的可用信息。 内容包括:结构防火的背景信息，以及火灾对不同类型建筑的影响，标准耐火设计和结构防火工程设计之间的主要区别，-评估因火灾暴露引起的结构热边界条件以及基于材料热特性进行传热计算的指南、火灾暴露下结构的性能目标以及可用于量化结构对火灾效应响应的分析技术。 本实践手册是结构工程师、建筑师、建筑官员和关注基于性能的结构防火设计的学者的宝贵资源。

Prepared by the Fire Protection Committee of the Structural Engineering Institute of ASCEStructural Fire Engineeringprovides best practices for the field of performance-based structural fire engineering design. When structural systems are heated by fire, they experience thermal effects that are not contemplated by conventional structural engineering design. Traditionally, structural fire protection is prescribed for structures after they have been optimized for ambient design loads such as gravity, wind, and seismic, among others. This century-old prescriptive framework endeavors to reduce the heating of individual structural components with the intent of mitigating the risk of structural failure under fire exposure. Accordingly, the vulnerability of buildings to structural failure from uncontrolled fire varies across jurisdictions- which have differing structural design requirements for ambient loads- and as a function of building system and component configuration. As an alternative approach, ASCE Standard 7-16 permits the application of performance-based structural fire design (also termed structural fire engineering design) to evaluate the performance of structural systems explicitly under fire exposure in a similar manner as other design loads are treated in structural engineering practice.Structural fire engineering design is the calculated design of a structure to withstand the thermal load effects of fire, which have the potential to alter the integrity of a structure, based on specific performance criteria. This manual, MOP 138, addresses the current practice, thermal and structural analysis methods, and available information to support structural fire engineering design. It covers- Background information on the protection of structures from fire and the effects of fire on different types of construction,- Key distinctions between standard fire resistance design and structural fire engineering design,- Guidance for evaluating thermal boundary conditions on a structure because of fire exposure and on conducting heat transfer calculations based on the material thermal properties,- Performance objectives for structures under fire exposure, and- Analysis techniques that can be used to quantify structural response to fire effects.This manual of practice is a valuable resource for structural engineers, architects, building officials, and academics concerned with performance-based design for structural fire safety.
