Expansion joint in a 100 m long RC building

[nivoo_boss]

Hey everyone!

So I have to design this two-storey storage building. The second floor is made of precast RC beams and support ~12 m 400 mm hollow core slabs. The roof is supported by ~12 m steel trusses. The building is about 10 m high.

Anyway, my question - is an expansion joint needed in a building this long (about 100 m) or is there some way to calculate the forces in columns from the shrinkage of concrete? Below is a screenshot from the model, it's still a work in progress though. In the model RC beams are colored pink and hollow core slabs are orange/yellowish. On grid L7 there is a firewall.

Are there any other special considerations with a long building like this? I'm in Estonia, no seismic design needed here.

My points,

- If the bldg is unheated (warehouse and probably unheated ) and the columns fixed, i would provide an expansion joint..

- the location for EJ could be at firewall ..( double the columns and beams at firewall axis and fire wall would be constructed at one side )

- you may perform analysis and see if needed ..


..my opinion.





If you put garbage in a computer nothing comes out but garbage. But this garbage, having passed through a very expensive machine, is somehow ennobled and none dare criticize it. ( ANONYMOUS )

It is actually heated. It's sort of a storage/manufacturing building.
