No sound as soon the interview (i.e. 2 people in view) starts?? There is sound at the start and end of the clip when there is just 1 person in view. I would to love to hear what is being said (switching on subtitles is not quite the same due to transcription errors). NB Very interesting subject, thank you!
1- A single GL beam can be cantilever at the side of the column as well. Therefore, that is not an advantage only to the double beams. 2-The double beams method can create some fire safety for the top side of the column. But, double beams methods make the beam weaker along span in a fire event and increase the char rating of the beam significantly. It means double beams has a faster charring rate than a single beam when they have a similar size section area. Therefore, that is a disadvantage to the double beams. 3-Always double beams will be thicker than the width of the wall underside, which is an architectural disadvantage to the double beams compare to the single beam. 4- Two single beams have a higher load-carrying capacity than this double beams system, which is the cost-efficiency disadvantage of the double beams compared to a single beam. Finally, I think double beams method will increase number of required fixings/screws.
Great videos, keep it up! It looks like these mass timber buildings hold up well to 1st instance of fire. How do they fare for subsequent fire events? 2nd or 3rd fire events?
As with any structural material, evaluation and potential repair may be necessary following a fire event. Some mass timber members are over-sized to provide a wild charring layer, so that charred layer may be able to be removed and replaced with new wood, without needing to remove the entire wood cross sections.
I have studio review in 2 days using mass timber. Wish I would have seen this a month ago!
Bummer, best of lick with the studio. Hopefully the video is still helpful!
Is the double beam system also an option when combined with concrete columns?
