Re: Load - Occupany Live Load

[Subject Prev][Subject Next][Thread Prev][Thread Next]
With my experience with fitness centers, the free weight area is not the problem but the aerobics area is. I have (as well as the building officials reviewing my work) have been concerned about 150 (usually overweight) people jumping up and down creating quite a dynamics problem.
