parking garage
(OP)
have someone some experience with OPEN car storehouse.
OPEN - means that I must take care on temperature influence.
My object is 180x120m big, and have 4 floors.
It is concrete structures, and the space between column is 10x7.25m.
Here is the question for you (to help me):
- live load for car storehouse (or parking garage) is ?? (looking for minimal)
- Do you consider the temperatute loading ??
- is 60x60m to big for one field
thanks bart

but don't for get about contraction also. Joints should be flexible for expansion and contraction

Is this proposed structure going to be post-tensioned (P-T) concrete? If so you need to carefully consider restraint from stiff columns or walls, most especially at the perimeter.

RE: parking garage
Temperature differential should definitely be considered for the roof. Temperature shortening as well as shrinkage shortening should be considered in the design of expansion joints and of columns and connections if long pours are done or stiff columns connected.
60m by 60m is propbably too much to pour in one pour, especially on a project where there are going to be multiple pours on each level. The normal limit woulod be about 1000 to 1200m2 per pour. Also, if post-tensioned, 60m is far to far to stress from one end, as would be required for connecting slabs. 60m lengths of slab will also cause severe cracking in columns.

I agree with rapt, you should design to your local Code requirements, or to a recognized foreign code.
