This Special Issue brings together emerging innovations and practical advancements that are shaping the next generation of timber construction. From breakthroughs in material science to high‑performance structural systems, our goal is to highlight how wood can contribute to safer, more sustainable, and more efficient buildings.

We invite contributions across the full spectrum of research and practice, including:

  • Original research on materials, systems, testing, modelling, and structural performance

  • Comprehensive literature reviews that synthesize current knowledge and identify future research needs

  • Research case studies demonstrating innovative methods, analytical approaches, or performance insights

  • Practical/industry case studies showcasing real‑world applications, challenges, and lessons learned

This Special Issue aims to serve as a platform for researchers, practitioners, and industry partners who are advancing the science and practice of building with wood.

If your work aligns with these themes, we warmly welcome your submission. For more details, please visit the Special Issue page (https://www.mdpi.com/journal/buildings/special_issues/F5WJ269YMS), or feel free to contact me at zhiyong.chen@fpinnovations.ca.

This is an important workshop that has a great impact on the mass timber research in the U.S.

Hope to see everyone in Madson WI in November!

Contact Marco Lo Ricco via email: marco.loricco@usda.gov for details.

They also need student volunteers to help plan and do pre-workshop surveys 

Please check out the attached flyers for details and how to get involved

However, it is unclear if it is necessary to caulk the joint between the beam/column or beam/beam. It seems to be based on jurisdiction / engineering judgement (and theoretically, would be in scope of the architect to determine - but in mass timber fire has a more direct structural impact thus it's becoming more important for engineers to be involved in rating discussions). 

I'm curious what resources anyone here points to to justify the need or lackthereof of caulking at these connections?

If memory serves it is set at 5% (5th percentile) for characteristic values, which means if you pick up a wood and test it, there is 95% chance your test value will be higher than what is used in design (so design is conservative).

Do we know what is the statistical information on the values listed in NDS with regard to testing results? @drammer

say I have a beam start from 20" on one end and go to 10" on the other end, what depth should I use to go into the CL calculation?

Using 20 is apparently conservative and OK, but is there any explicit rule for that?
