ASCE 7-16 4.9.3

thread176-493778

ASCE 7-16 4.9.3

ASCE 7-16 4.9.3

(OP)
Hi all, my first time posting.

In overhead crane runway design, I am hoping someone could help me understand why the vertical impact % is applied to the self-weight of the crane and hoist, when the weights are not changing.

RE: ASCE 7-16 4.9.3

Because the impact force is related to the mass/weight of the member. You're not increasing the self weight, you're applying a live load that is a percentage of the self weight.
