Short beam for arrangement

[injonil]

I am going to install a 3200mm long HEB 160 that will rest on steel columns at one end but will end up in a corridor opening at the other end. Therefore, I will place a short beam in the opening (900mm) for the beam to rest on.

The HEB-160 beam will replace a load-bearing wall and support a floor joist, plus every other floor joist is also a roof truss (Swedish roof truss).

Can anyone provide guidance on how strong the support beam needs to be? It will be approximately 1200mm long including its own support.

But continue with HEB 160 beam.

Well, I'll do it unless someone can provide an answer on what is sufficient for this short span...

However, I don't have 1200mm left from the existing beam and will go to the scrapyard to get a new beam for this purpose. Of course, I can manage with a slimmer dimension; the question is just how slim is safe without having to calculate it.

Learn something new (or refresh the old knowledge):

I personally feel strongly that I want/should/can refresh my old knowledge, I actually knew this once upon a time. :|

Unfortunately, I haven't even attended technical high school, but of course, you can learn if you want to. However, I don't really have the time to learn it now for this occasion, but I agree that it would be fun and sensible to know!

 

[Mikael_L]

I started to take a look at it now. Damn, I'm so rusty ...

But if I get some free time tonight, I think I'll try to do some quick calculations.

 

[injonil]

It would be fun to get an indication! I want to know which beam I can use as the weakest without compromising the rest of the construction.

Otherwise, I'll do as Protte suggests and go all out

Guessing without knowing that it works well with everything from Hea 100 and upwards, but weld in a liver plate where Heb160 ends up.

Did a quick calculation, and Hea 100 comfortably agrees, can calculate more accurately tomorrow and see what the smallest possible is.

How wide is the house? In other words, how many square meters of the upper floor rest on the beam?

 

[Claesk]

Also need a beam. About 4 meters long. Will remove a load-bearing wall. Only roof above. Single-story house.

 

[Mikael_L]

Need a beam too. About 4 meters long. Will remove load-bearing wall. Only roof above. Single-story house.

Available at e.g. Tibnor.

 

[injonil]

Did a quick calculation, and Hea 100 holds with a good margin can calculate more accurately tomorrow and see what the smallest possible is.

How wide is the house? In other words, how many square meters of the upper floor rest on the beam?

Thanks The house is almost 7m wide, but knee walls make the floor on the upper floor only 4.2m wide.

 

[JOW]

Why choose an H beam in these situations?
Isn't it simpler with a square tube? VKR or KKR?

Then you shouldn't need to weld on a web plate, right?

 

[injonil]

If there is any advantage with a square beam compared to an H-beam for this purpose, then I will choose that instead, no problem

With a 1200mm span, I wouldn't be worried about using an HEA100 in this application without lateral bracing.
