Story shear in ramps

[slickdeals]

Greetings,

I am designing a parking garage with ramps in both directions (dog-legged). How do I determine my diaphragm extents? Is it okay to take half the weight of the ramp to the story above and below to calculate story shears?



Thanks

Yes, we have done this way before. Seems appropriate.

I think this is the only way you reasonably can do it. Center of inertia (mass) is at the center of the ramp.
