Question regarding free height in residential buildings(?)

Question regarding free height in residential buildings(?)

Question regarding free height in residential buildings(?)

This is sort of an odd question, what part of the code regulates the allowable min. height between floors (I'd refer to it as free height, although I'm not sure exactly how they refer to it in english). In my country we have a required min. height in residential buildings of 2.20 m meaning that the distance from the roof or joist's bottom to the floor must comply with this. Anybody knows what entity or part of the code regulates this and what are the required values?

RE: Question regarding free height in residential buildings(?)

Under the IBC the height is controlled per an engineered design.
Under the IRC the tables control the wall height, but you can still do an engineered design for higher.
The ASCE does not state a maximum allowed wall height.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

RE: Question regarding free height in residential buildings(?)

Thanks for your prompt reply, I do think there must be a minimum required height for service conditions (probably dictated by the local construction codes rather than the design codes (?)), I don't think people would feel comfortable under 7' ceiling heights. Somebody told me that there actual limit is somewhere around the 2.10m (6 8") which would seem reasonable in my country but here it would certainly be too low (considering the median height). The purpose of this thread is because I'm designing a wood residential complex, and I was given the estimated floor heights (10 1') but I have +30 ft spans and I don't want to end up with really deep members just to comply with deflection limits and then end up with a building for midgets (no offense to little people or dwarves or whatever they like to be called).

RE: Question regarding free height in residential buildings(?)

In the US you would check the IBC for min. heights of rooms. In other countries just check the basic building code. This would not be a structural question.

I do know that on a stairway you can go down to 6'-8" off the tip of the tread up to the ceiling.

RE: Question regarding free height in residential buildings(?)

I know this wasn't exactly a structural question but it's concerned with the structural layout of the building (plus the other forums seem to match even less, even the code ones considering I had already done a search within the codes before posting)
