seismic joint gap for steel building

[nikgr82]

Hello to everyone.

Does anyone know what is the maximum length/width ratio for a single-storey steel building above which we should place a seismic joint gap to seperate the building into parts ?

If you could give me a code reference i would really appreciate it. I use EC3 and EC8.

I didn't know that there was such a ratio.

I always looked to disconuities, steps, geometry, and differing lateral systems as to where to place any joints.

I guess i did not write the thread correctly.


Whati i mean is whether there is a maximum length/width ratio or generally a maximum length for steel buildigs ?

If we overcome this length we must use a seismic joint gap.

For example a steel building with a width of 10 meters can have a length of 100 meters and be analysed as one part?

I would usually break a long struture into two for volume change issues as well as what has been previously mentioned.

Diaphragms will need to be modelled as flexible.
