Wind load for Small room inside a huge structure
Wind load for Small room inside a huge structure
(OP)
I have a a small room inside a huge structure (factory) but not connected to any part of the big structure I don't know if I should take in my consideration the effect of wind load or not because the big structure is already designed with wind load

If not, the large building will shield the small building if it is inside the big building.

As JAE indicated, there's the code provision for 5 psf horizontal load on interior partitions.
When you look at the equations for MWFRS and C&C Wind loads, there's a component for interior pressure effects, GCPi.
This load is greater than 5psf (5.7psf for my recent calcs with GCPi = +/- 0.18) but ASCE 7-16 is going to add a category for partially enclosed buildings with GCPi = +/- 0.55 (17.5 psf).
How is it that we design our C&C for an internal pressure of 5.7 (soon to be 17.5), but our interior walls for an internal pressure of 5psf?

The minimum interior pressure as I have always known it was 5 psf. It is stated that way in the code. But that is exactly what it is named, a minimum. It is up to the engineer to decide what an appropriate loading is for their conditions, but it must be at least 5 psf.

I haven't dealt with "tunneling" before. Perhaps i under-designed them?

The partition between stalls of a carwash is a good example of that.

1607 LIVE LOADS
1607.13 Interior walls and partitions. Interior walls and partitions that exceed 6 feet (1829 mm) in height, including their finish materials, shall have adequate strength to resist the loads to which they are subjected but not less than a horizontal load of 5 psf (0.240 kN/m2).
RE: Wind load for Small room inside a huge structure
I see:
5 psf in 1607.13 under LIVE LOADS in IBC 2009
5 psf in 1607.14 under LIVE LOADS in IBC 2012 & 2015
5 psf in 13.5.8.1.3 for seismic in ASCE 7-05.
I don't see this provision in ASCE 7-05 for wind. Can anyone pin-point it for me?
Thank you!

I would consider designing the walls for a partially enclosed condition if the building meets the criteria to being classified as such.
