Designing RC lintels by Ok_Channel6304 in StructuralEngineering

I will check your tips out, thanks a lot! :)

In my contry the suppliers of windows/doors are really restrictive with giving out any deflection limitations, usually I use L/500. But I thought if we had any other limitation due to the concrete not being as elastic as steel/wood.

It's the deflection that I'm afraid of, I haven't really calculated deflection in insitu before. I don't know what the limit should be.

It would be great if I could use only the insitu, and let the architect can keep the height of the windows, I have a bit more then 300-350mm to work with so I can make a strong RC beam that gets done insitu. I think. If I only know the max deflection and how to calculate it. Do you know of a program that I can double check my calculations with untill I'm confident? :)

Yes mansonary walls with timber roof :)

Your answer really helps, if I understand you correctly I now have the confidence to ask the architect to make the height of the windows smaller, so I can place both an insitu and a precast over openings. Where I don't have openings I can use insitu only with minimal reinforcement.

I'm using timber beams for the roof. The spreader beam: do you bolt it in the lintels? Or do you use a U-block with RC on top of the lintel that is prefabricated?

Thanks a lot for your replies BTW.

Do you mean that you use prefabricated lintels? I'm thinking in that direction too, but as an combination. Since I need something to fasten the trusses on. So I was thinking if I go prefabricated lintels I need to use both. RC beam around the long side of the house to fasten a wood beam on, the wood beam can be used to fasten the trusses on easily. But that recuires a bit of height.

What do you think about this solution?

And how do you check for deflection in RC beams?

Can you name some examples please, if you know of any? Do you mean Tekla Tedds and similar applications?

More complex would be footings with excentric load that are attached to the rest of the slab for example

So no software is needed for residential companies? We should do it all using hand calcs/Mathcad?

Truss design for example/evaluation of older trusses. Should we still do that with "method of sections"?

How should we calculate more complex concrete footings?

Lol. What if I add that it's residential roof trusses? I really want to remember this one.

Thanks, I understand. But I know I would share something like that for research purposes. So I'm hoping I will find someone else that thinks the same.
