Development of Fire Resilient Steel Connections using Hybrid Testing

Benson Steel是一家加拿大领先企业，专门从事钢梁到柱连接的创建和开发，以支持结构工程从业者。然而，最近出现的情况是，随着人们热衷于设计钢结构建筑以确保耐火设计，人们对钢结构连接在真实火灾中的潜在行为缺乏足够的了解，从而使这些创新设计成为可能。一种称为混合测试的稳健建模和实验技术将考虑各种连接如何在实际火灾中观察到的复杂热负荷下执行。这项研究旨在了解在真实火灾中影响钢连接实际行为的基本机制(火灾动力学、热传递、连接固定)。将制作一个用于设计的计算工具包，并将提出一种对复杂热负荷配置具有弹性的最佳连接类型，如在真实火灾中看到的那样。在整个项目的同时，所有研究团队成员将使用计算工具包为建筑设计实例做出贡献。反过来，这将有助于发展本森钢铁公司及其提供替代材料解决方案和弹性技术的能力。

Benson Steel is a Canadian leader that specializes in the creation and development of steel beam to columnconnections in support of practitioners in structural engineering. However it has recently emerged, that with adesire to design steel buildings to ensure fire resilient design that not enough is understood about steelconnections underlying behaviour in real fires to permit these innovative designs. A robust modelling andexperimental technique, called hybrid testing, will consider how various connections perform undercomplicated thermal loading that can be observed in real fires. This research aims to understand the underlyingmechanisms (fire dynamics, heat transfer, connection fixity) that contribute to the real behaviour of steelconnections in real fires. A computational tool-kit will be produced for use in design and an optimumconnection type will be proposed that is resilient to complicated thermal loading configurations as seen in realfires. Concurrent with the full project, all research team members will contribute to building design examplesusing the computational tool kit. This, in turn, will help to develop Benson Steel and their ability to deliveralternative material solutions and resilient technologies.
