Need Help To Design Support Stucture For The 1 Floor (Terres) Shed

I will not contribute to this folly. Hire an engineer.

Or, do it on the cheap.

Something like this ?

Thanks you so much,

But in this they have not mention about the factor related with my calculation. I am looking for the how to decide the how many supports I should provied. Please see this picture

I can try later to get better numbers for you, but for now, in very rough terms, the allowable span for structurals is about 30x their depth. For 40mm joists/rafters, this would be ~1.2 meters. If the loads are light, it can be more. In your case, there may be almost no live load, and only the weight of the roof itself. This depends on how much snow or wind you might receive.

I think you may just have the wrong idea about this site. Generally speaking we don't crunch numbers and do design work just for fun. if you had a more specific question you'd get a real answer, but you're just looking for a few thousand dollars of free work from people who have little or no interest in working for free...at least not me. good luck and don't forget to budget for rafter hangers and 3500 PSI footings

Yes, you need help. You need the help of a structural engineer that understands your soil condition and the nominal loading that local weather will give you.

Maybe, a little more clarification is in order...

You wrote ''terres'' but did you actually mean ''terrace'' or ''terraced''? If so, then how much , and in what ways?

Is this stucture to be used primarily for human habitation, or for storage of materials, or both, and/or what other function(s) ?

How heavy is/are the (contents) to be?

By the way, a 2'' diam. GI pole is more like a fence pole, not much of a structural support...

Is it all to be welded, bolted, and/or with some other means of connection(s) ?

Oh, how much of what kind of land is the structure to be ''sited'' on? Is it earthquake-prone? Is it subject to heavy rainfall and/or what other hazard(s) ?

What utilities will it require?

And, what exactly to you mean by ''trangular fixcture''?

Has anyone else done this in your vicinity?...

Consult a qualified building designer locally. All works will need to comply with local Planning laws and, if intended to be habitable, local Building Regulations.

Thanks for all,

Please Don't get me wrong..! Yes, This is '' terrace '' shede. Use of this is only to cover the concrete 1st floor base. Because, it's open space which I am going to use for an event, just to rest our self from work, Use for having a cup of tea in the evening Or glass Beer............!

I AM NOT DOING FOR SAVING SOME MONEY BUT FOR ' TO CREATE SOME BY MY HAND = SELF SATISFACTION'

The reason why I am asking this Question on CR4, Because I know here I will get the Best and right answer.

So, this is part of house is based on concrete construction.

1. Center Height of the shed is 10 Ft., where as end of both side is 8 ft.

2. This place is free OR not for earthquake condition.

3. Roofing is made up of aluminium colour coated sheets. So, the weight of the shed is very less (Apx. = 260 kg.)

But where I was confuse, how many cantilever should be provide to shed

I decided,

1. 3 cantilevered edge.

Direct base for roofing sheet. and before vertical support.

This diagram is much more explanative than just a verbal description. Thanks, it clarifies a lot.

I should also say here that the structure portrayed therein could be improvised with less costly and less heavy (but less structurally strong) threaded plastic piping/tubing and plumbing fixtures. The added advantage would be that, if configured for it, said structure(s) could be taken down, relatively easily, and repaired relatively quickly, if damaged, and not be subject to more strict structural scrutiny that a more permanent (shelter/screeen/cover) would be...

Here in the USA we have the UBC to reference for determining the allowed span for any/all building materials.

The information is displayed in a "lookup" table format that is easy to read and understand.

I would suggest that you access your local code (if existant) and design the building accordingly.

The number of trusses (trianglar fixtures) is dependent on two things:

1. The local building code constraints.

2. The roofing size/width , the type/design of roofing material, and the wind loading factor for your respective area.

If there is not any code where you are, my advice is to contact the manufacturer(s) of the materials you are using and follow their directions.

I'm not touching this one with a ten foot pole, no puns intended.

If this is a one time event, why not just rent a tent with open sides as appropriate, otherwise you need a local Structural Engineer?

The Devil is in the details.....

Ah yes empirical engineering!

Try laying the material you propose to use on the ground with supports under it to mimic the spans. Then stand on it. see how it behaves.

It's just a shed roof for crying out loud!

I'm sure there are lots of similar structures around your locale that you could look at made from the same locally available materials. You should be able to see what works right with what is available where you are.
