Browse Forums General Discussion 1 Nov 26, 2020 5:13 pm My plan has some external posts on it which support the first floor. The first floor overhangs the ground floor (first floor is the blue outline). The ground floor has two bifold doors that meet in the corner, so there is no support in that corner. The plan currently has 125mm cypress for the posts. I'm concerned about longevity. I also want to get rid of one post as it impacts negatively on where the bifolds meet and open. Is steel or timber the way to go? Consider lifespan, environmental impact, cost, etc. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Timber vs Steel Structural Posts 2Nov 26, 2020 8:17 pm Hey harleyca Welcome to the forum Definitely steel posts and you'll need a steel lintel/beam to support the floor above and The bi-folds. You're at the engineering consulting stage Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Timber vs Steel Structural Posts 3Nov 26, 2020 11:14 pm Bi-folds in your configuration: you will probably only use them twice or thrice to take pictures before selling your house. Otherwise, they seem to be completely impractical: 3 of them, they will be quite heavy at 3.2 m (and no hydraulics, so will be quite a workout opening them back and forth every day), no fly screens, and based on the square area, your glazing will be driving off most of the heat from your house during winter and most of the cold in the summer, which in addition to having huge steel lintels over, will take an effort to reach even six stars. Plus bringing in all the noise from the outside.

However, as you increase the spans then Steel beams and posts may be your only option. I'm in the same situation for the custom design of my shack. My advice is to simply define what your requirements are and leave it to the (Structural) Engineer to design the most appropriate solution for your particular requirements.

Here Need inspiration for a sun shade? Nice 3D Artistic Bim Model.. but imo It lacks Structural BIM Integrity. Care to share the structural Framework, ie, timber, steel, concrete, costs, etc ? Most battlers and punters are tired of seeing House renderings which wind up costing them an arm and a leg Once the upgrades, variations, engineering and 2nd Stage Quantities are completed.

Cheers Chris 100% on the money! I’m only a Chippy but when we have to work off these overly simplified images, it almost always breaks a few hearts! I call it the 3D/tech shock lol Hi I am wanting some opinions about the build of a steel shed I am going to get one about 4.5 x 2.5 m steel shed and the height will be about 2.3-2.4m high The one I am… 0 14458 You’re on the right track, wire brush in a grinder then a zinc rich epoxy primer then a top coat of some sort, like a waterproofing membrane. Raising the concrete would… 1 7035 This is 100% true. You can not hang anything on steel frames. very frustrating 8 8045 |
