Towards a performance based fire design framework for resilient composite steel deck construction in Canada

加拿大传统的钢桥面板结构防火设计是规范性的。这种设计过程依赖于简化与孤立的建筑构件设计的基础上隐含的火灾关系。鉴于全球的进步，这种设计程序可以被视为限制性的，结构材料利用不足，浪费防火材料，甚至有时不安全。基于性能的防火设计（PBFD）方法依赖于合理理解火灾和结构界面。加拿大现行的复合钢桥面结构建筑规范是根据基于目标的规范编写的，以允许在结构中进行防火安全的替代解决方案设计。然而，很少有指导从业者如何解释和制定一个替代的防火设计解决方案的复合钢桥面结构，健全的实验，以协助数值验证，以及非常少的信息，可用于证明钢结构在火灾中的弹性。本研究的目标是开发新的结构防火设计指南，为加拿大咨询从业者遵循的安全，弹性和经济的设计复合钢桥面结构。这将是与加拿大钢铁行业的主要利益相关者合作：卡尔顿大学;加拿大钢结构研究所（CISC）和Entuitive。CISC是一家著名的组织，为加拿大的钢结构组织提供支持;而Entuitive是一家专注于钢结构的设计咨询公司。研究的总体目标是：（1）探索加拿大当前使用的消防设计方法的子问题;（2）通过实验，评估和研究钢结构的结构火灾弹性行为;（3）发展，并发布钢框架和复合桥面系统的替代结构设计解决方案，供加拿大使用，以提高最佳实践和经验证的数值建模能力在卡尔顿大学和国外的新实验的支持下;和（4）帮助建立一个适当的PBFD框架的投入，考虑到未来的加拿大代码和标准。

Traditional structural design for fire safety of composite steel deck construction in Canada is prescriptive. This design procedure relies on simplification with isolated building components being designed based on implicit fire relations. In light of advances globally, this design procedure can be viewed as restrictive, under-utilizing of structural materials, wasteful of fire protection material, and even at times unsafe. The Performance Based Fire Design (PBFD) methodology relies on the fire and structure interface being rationally understood. The current building codes for composite steel deck construction in Canada are written to allow alternative solution designs for fire safety in structures under the objective based code. However, there is little guidance for the practitioner on how to interpret and formulate an alternative fire design solution for composite steel deck construction, sound experimentation to assist numerical validation, and very little information which can be used to demonstrate the resiliency of steel construction in fire. The goal of this research is to develop novel structural fire design guidance for the Canadian consultancy practitioner to follow for the safe, resilient, and economical design of composite steel deck construction. This will be a collaboration with the key stakeholders in the Canadian steel industry: Carleton University; Canadian Institute of Steel Construction (CISC), and Entuitive. CISC is a reputable organization which supports structural steel organisations in Canada; while Entuitive is a design consultancy firm with focus on steel construction. The overarching objectives of the research are to: (1) explore sub-issues with current fire design methodologies in use in Canada; (2) with experimentation, assess and study the structural fire resiliency behavior of steel construction; (3) develop, and publish alternative structural design solutions for steel frame and composite deck systems for use in Canada to advance best practice and competency with validated numerical modelling supported by novel experimentation at Carleton University and abroad; and (4) help establish input for an appropriate framework for PBFD for consideration into future Canadian codes and standards.
