First time learning about hanging beams, but this video is great. If the hanging beam isn’t meant to support any roof load, does the hanging beam have to be resting on walls on both ends of it? If you wanted to remove one of the walls at the end of a hanging beam, can the continuous ceiling joists themselves support the hanging beam?

Hi Mate, thanks for your comment. The hanging beam needs to be supported at both ends, if you want to take out the wall you will have to install a counterbeam to carry the Hanging Beams. Hanging beams are only required when the ceiling joist can't span the required distance, they do not support the hanging beam, the hanging beam supports the ceiling joists. Hope this helps

Really helpful videos. Appreciated. Can you please tell why have you put small timber pieces(timmers/outriggers) over top plates? Is the spacing of Joists 600mm as the rafter spacing? Thankyou.

[@Buildsum]

HI Zeeshan The small pieces on the hip end are to carry the ceiling sheets and not interfere with the rafters at the hip end of the roof. Yes ceiling joists are spaced at the same spacing as the rafters. Thanks for your comments hope this helps

Great videos, really glad youre showing us these videos. i am curious as to why you had 2 of the rooms ceiling joists running perpendicular to the rest of the rooms. Was there a reason you did it or was it simply for exercise purposes? thanks

[@Buildsum]

+Josif Nguyen Hi Josif It was mainly done for exercise purposes however it is possible. The Timber Framing Code state "ceiling joists shall be in single lengths or spliced in accordance with Clause 7.2.4.2, and at the same spacing and in the same direction as the main rafters so that they may be fixed to, and act as ties between, the feet of pairs of opposing rafters" The joists in the example fall under the hip and and therefor would not tie the main rafters. Also by turning them the span is shorter for the joists. Hope this helps

[@josifnguyen8911]

Yes it does, much appreciated.

Great Video mate! Just wondering if you can address me that 1.7 m and 2.2 m ceiling joist spans in AS 1684? Thanks

[@Buildsum]

Hi Al, as the span tables are part of AS 1684.2 I can't give you a copy, however, there are plenty of free versions around. This page has a pretty good list of span tables and software that can help you work out the span you need. www.woodsolutions.com.au/articles/span-tables-and-software The other option would be to go to your local TAFE library ( if you are a student) or your local council library.

[@aljafari2364]

I have the span tables in office but never used them, mostly bcuz we use Hyne software. Just wanted to see if there is a rule that you said it's based on the span tables.

[@Buildsum]

Hi, AS 1684 sets out general rules for the use and installation of the timber members and also tells us the correct span table that we should be using. So for this video I used the Span Tables for MGP10 timber in the N3 wind zone so those figures ( 1700 - 2200) come from that set of span tables, each timber grade and species have a separate set of span tables so it will depend on the timber you intend to use

Good videos mate! My understanding of the maximum continuous span is kind of different. Like if you use the hanger, the continuous span of one of the room on the left bottom should be 3.5 rather than you said 1.7m which is excessed of maximum 2.2m. Is there something wrong of my understanding of the continuous span ? Thanks!

[@Buildsum]

Hi Mate, for the room at the bottom left the Single Span would be 3.5m however, by adding the Hanger the required Continuous span becomes 1.750m while we could go all the way up to 2.2m in this situation

Thanks Mate.
