LUNCHTIME WEBINAR - 28th OCTOBER 2020

We are pleased to inform you that our next FABIG Lunchtime Webinar will cover 'Introduction to structural fire engineering' and will be given by Bassam Burgan from The Steel Construction Institute (SCI) on 28th October 2020 from 13.00 GMT.

Please note that this Lunchtime Webinar will exceptionally end at 14.10 GMT.

For additional information and registration, please go to the Events section of the website.

Abstract:

Structural fire engineering is one of the most important concepts in the provision of overall fire safety. It is widely regarded as a passive measure i.e. something that helps a structure withstand a severe fire, rather than an active measure which warns of, or intervenes to reduce the effects of a fire. As a fire develops, the structural elements affected by the fire will start to get hot; there are two consequences to this. First, the structural material will start to expand and depending on how structural elements are supported, this manifests itself as an increase in deflection and/or thermally induced forces and moments where a member’s expansion is restrained. Secondly, the structural material properties start to degrade as the temperature of the structural elements increase. The rate at which these two effects contribute to the performance of the structure depends on the rate at which the structure heats up.

A range of approaches can be used to ensure satisfactory structural performance during fire. These vary from simple prescription e.g. the required thickness of applied fire protection for steelwork, or the cover to reinforcement in concrete, to more complex analytical calculations. Irrespective of the type of approach, a three-step procedure is usually followed: (1) determination of an appropriate fire exposure to apply to the structure; (2) determination of the thermal response of the structure; and (3) determination of the structural response.

This webinar will describe the principles of structural fire engineering and the three-step procedure noted above. These procedures will be illustrated using a number of simple examples. Whilst reference will be made in some instances to the Eurocode for fire design of steel structure (EN1993-1-2), the principles presented will be generic and widely applicable.

FABIG WEBINAR SERIES

We will be organising lunchtime webinars every two weeks whilst working life remains disrupted by measures to combat the COVID-19 epidemic. Such measures either prohibit or make inadvisable large meetings such as our Technical Meetings.

We are now looking for presentations covering topics relevant to the theme 'Robust Principles for Safe Design against Fires & Explosions based on Experience' for our next Webinar Series. As such, please do not hesitate to contact us at fabig@steel-sci.com if you or one of your colleagues would like to give a relevant presentation.

Take care and stay safe,

The FABIG Team
