Teacher’s thoughts after the Fire simulation -course

Alltogether 14 students passed the Fire simulation -course this spring. The course was about fire and evacuation simulations, focusing on the simulation technology.

Congratulations to all our active students!

In the final project of the course, the students had to perform a fire and evacuation analysis of Aalto University’s new building, called Väre. Actually, just the part of the building which contained the lecture halls and large atrium. The project works were evaluated based on the technical aspects of the simulations, reporting quality and critical assessment of the results. The actual analysis outcomes, such as fire conditions or evacuation times, were not really evaluated, as I did not have a ‘correct answer’ to provide. Also, as we did not really cover the performance based design process in this course, the students were on pretty much on their own when making the modelling decisions.

However, I thought it would be interesting to see how the results are distributed. The figure below shows a summary of ASET vs. RSET values extracted from the students’ reports. What surprised me, was the fact that the scattering in the fire simulation results, i.e. the ASET value, was so large. OK, among the results there are some that included a clear error in fire specification. But anyway, I would have expected that the scattering would be more in the evacuation simulation results.

As a teacher, this was a very valuable exercise to me because it gives me a reference point when designing a future course about ‘Fire risk and evacuation analysis’, to be organized in fall 2017. Justification of fire scenarios, critical review of modelling decisions, and self-evaluation will become topics there.

Participation in COST Action FP1404 expert meeting on fire safe use of bio-based building materials

Dr. Kaiyuan Li has been invited together with 14 other European experts to the expert meeting on numerical simulation in terms of fire safe use of bio based building within COST Action FP1404 – Fire Safe Use of Bio-Based Building Product.

The two-day meeting was held at the University of Ljubljana, Faculty of Civil and Geodetic Engineering, on 25th and 26th of January 2016, Ljubljana, Slovenia. In the meeting, Dr. Kai gave a lecture entitled as “Modeling pyrolysis of medium density fibreboard-pyrolysis modeling present and future” to the participants.

15 experts from all over Europe participated in this Expert meeting and discussed the state of art, actual challenges and new approaches to deal with tasks related to different aspects of the fire safety of bio-based building products.

 About COST FP1404 – Fire Safe Use of Bio-Based Building Products

Bio-based building products have a very long history, e.g. as timber structural members. Combustibility was the main reason why bio-based building materials were banned from many applications. When performance based design (PBD) became possible many building regulations opened the market for bio-based building products. However, large differences between regulations in countries exist and the use of combustible building products is still very limited.

This COST Action provides a platform for networking, exchange and collection of performance data, experiences, authority- and climate requirements which affect the design with respect to the Fire Safe Use of Bio-based Building Products. By systematically organization knowledge in this area will advance at a significant higher rate. The Action will Exchange researchers, organize Workshop and create comprehensive dissemination material.

The Action has three technical Working Groups (WGs) and a WG for Dissemination.

Chair of COST Action FP1404 is Joachim Schmid from Department of Civil, Environmental and Geomatic Engineering, ETH Zurich.

Further information is available online (www.costfp1404.ethz.ch).
