Workshop on Advancements in Evaluating the Fire Resistance of Structures

IMG_3385
Presenatations will be invited for full paper consideration in the journal, Fire and Materials

Dr. Gales will be chairing the Workshop on Advancements in Evaluating the Fire Resistance of Structures to be held Thursday December 6th and Friday December 7th, 2018. This workshop is sponsored by ASTM Committee E05 on Fire Standards and will be held at the Washington Hilton in Washington, DC, in conjunction with the December standards development meetings of the committee. The workshop will celebrate the centennial of the furnace temperature-time curve, which defines the thermal fire exposure conditions in ASTM E119 and other fire resistance test standards.

SFPE 12th International Conference on Performance Based Codes and Fire Design – Hawaii

Members of our team attended the SFPE fire conference in Hawaii last week. Team member Hailey Quiquero gave a fantastic presentation on modelling timber structures in fire from a FEM point of view. Her work is a collaboration with the University of Canterbury. Dr. Gales gave a presentation regarding steel connections based on team alumni Matt Smith’s work as he could not make the conference.

Research News for December 2017

Its been a busy few months. We gear up for the York University move in January. Our recent news includes:

Our team has won a number of recent research awards. Lauren Folk (now a graduate student on our team) won the Adjeleian Allen Rubeli Award Best undergraduate thesis 2017 at Carleton this fall. Her work is a collaboration with ARUP Fire that studied care home evacuation. We received three undergraduate research scholarships to study: Poverty in Canada, Timber in fire and GFRPs.

GFRPs, Heritage Timber, Education, Sustainable Concretes, Performance Based Fire, New Instruments and More!

Summer conferences

We have an exciting two weeks ahead. The research team will be visiting 4 conferences in the coming weeks to present 6 presentations. In addition we will have a 7th presented at ASFE and this will be announced at a later date. The below are brief descriptions of each. Open access versions will appear at a later date.

CSCE Symposium in Vancouver (May 31st to June 3rd)

Mass Heritage Timber Performance in Fire presented by Arlin Otto. The paper looks at a comparison of timber performance in fire of three unique types of timbers. The paper will also discuss adhesive bleeding seen in LVL panels .

Visiting the 911 Memorial in New York

WTCOn April 22nd, as part of a break from school at the end of the term, I took in the 911 Memorial Museum in New York. Not the most uplifting story to hear on a vacation, but a place I have been meaning to visit for years. I felt the museum to be very tasteful and a very important learning piece for those to learn what exactly happened that day (but ill argue understanding is different word to use here and a word I do not think we ever will be able to associate to that day). I feel it so important that people do be aware, today’s students that i teach, were far to young to know a world pre 911, they grew up in a different world. And from that the observations that you can learn visiting are just so much more important. The museum allows you to see quite a bit in terms of artifacts (fire trucks, and even the original foundations of the the tower). But it does educate what happened.

The Next Tallest Building in San Francisco

The Salesforce Tower will soon be completed and overtake the Pyramid as San Francisco’s newest and tallest building. I had a great oppertuinity to take a stroll through the construction area early this month and decided to highlight a few aspects of what i learnt and saw.

To me when i see cities like this, i am filled with creative inspiration. Its very easy to predict what the future skyline of San Francisco will look like. Where the tall buildings will appear (note that for now special planning approval must be given in San Fran), where the heritage will be conserved etc.

New Book on Post-tensioned Concrete in fire

A new book will be published by Springer titled; Structural Fire Performance of Contemporary Post-tensioned Concrete Construction. The book is available now. You can now order or download it here . The book features:

Our book is a concise account of PT concrete behavior in fire.
Our book is a concise account of Post-tensioned concrete behavior in fire. It is an essential first stop for new researchers and firms trying to understand this structural system in real fires.
  • A follow up to my highly cited Fire Safety Journal 2011 literary review paper – doubling the amount of tests analyzed;
  • New insights on bonded post-tensioned concrete construction;
  • Concise account of three large scale multi span post-tensioned concrete floor high temperature tests;
  • Updated five phased deflection theory on post-tensioned concrete continuous members in fire; and
  • New evidence regarding the origins of the standard fire test and discussion regarding that test’s relevancy to unbonded post-tensioned concrete construction.

The book aims to provide raw and valuable test data (restraint, tendon stress, slab temperatures, deflection etc.) from the three large scale tests fire tests on post-tensioned concrete. This information will be useful for structural design firms and researchers interested in understanding concrete structural systems in fire.

Developed based on my internationally recognized doctoral thesis (improving and expanding on portions from: chapter 2 – literary review and chapter 5- large scale testing of concrete slabs), the book represents a balanced and essential overview of the subject. Other chapters and portions of that thesis are being developed for publication elsewhere (future post to come).

The book was copy-edited by a communications intern on my research team and co-authored by the University of Edinburgh’s Luke Bisby. Our goal was to create a highly accessible book for entry undergrad students to senior engineers.
