Live Loads consider for design of Partition walls in Office building 2

[ARNAR]

Hello All,

Im doing the structural design of partition walls inside a office building. On the top of the wall a small book shelf attached to the wall .
while checking the code the min load is 0.25 kN/m2 ( As per IBC 2006 - 1607.13). I think its very small load. Can you suggest any codes for the design of partition walls??

Depends on the material of the partition wall, typically they are made of light-gage metal or wood studs. If they are light-gage than AISI S-100 the cold formed steel specification. If it is wood than AWC National Design Specification (NDS) would apply. Typically partition walls are non-load bearing and not included in the structural design.

Sometimes it would be hard to find those types of load recommendations for those kind of minor structures. So workout the loads in your way. For example assume book weights from unit weight of papers and thickness of a typical book and no of books, calculate the line load to be exerted by the shelf.
For any lateral loads , use a accidental loads from a foot bridge design code value

@Ash Thanks for the Help. We are using light gauge material for the portable partition wall. I agree with its non load bearing wall but it should have strength to resist the lateral load.

@Anushka123 Thanks. i will take the loads recommendation for barriers (.74 kN/m At 1.1m ht from floor , 1 Kn/m2 and 0.5 kn), Is it safe or we have to consider more loads.
what is the load recommendation for accidental loads for foot bridge??

"Portable partition wall"? Well, that's a game changer. Are you designing an office cubicle wall? Sounds more like furniture than a structure to me.

@MotorCity : Its not a cubicle wall ,its demount-able partition wall with book shelf.

The wall pressure, 0.25 kN/m2 ( 5 psf), is the minimum lateral load. The bookshelf is an eccentric gravity load. The load effects should be combined and compared with a manufacturer's tables, such as the SSMA catalog.

Bookshelves... floor to ceiling? Can have substantial loads, exceeding normal partition loading. If the floor is designed for full partition loading then it may be able to accommodate the added loading. I usually only use a fraction of the stipulated partition loading using a requirement for 'fixed' partitions (NBCC), with the owner sign off. With normal partitions if you have a fixed location, then future locations can be revised by engineering only. When you subtract the design live load from the area taken by the wall, there is very little added loading to the floor.

Some building codes in the US list library bookshelves as a live load with a density of 65 pcf.

For California Hospitals, the CBC Table 1607A.1 footnote n has loads for shelves,

https://codes.iccsafe.org/public/chapter/content/1945/

For Paper Media: 12" deep shelf = 33 plf; 15" deep shelf = 41 plf, and racks & cabinets = 33 pcf
For Other Media: 20 psf or 20 pcf

@Nirmal
The accidental lateral loads are as follows

According to Light bridge manual Australia, It is 10% of vertical load. So in this case you can assume a vertical load from a man or from a desk
According to Scotland manual it is 74kg/m

@ RPMG @ dik @DETstru @ wannabe @anushka: Thank you so much for your suggestions and advice.

I got a code reference for Internal non-load bearing partitions – DIN 4103-1
