High Rise Drift
High Rise Drift
(OP)
I am trying to get a handle on hi-rise drift and i have two questions considering a 500ft building w/ concrete shearwalls:
1. is 3/8" interstory drift too strict for hi-rise buildings with shear walls? what is more appropriate for hi-rise?
2. is it appropriate to evaluate 10-year storm drift using something greater than the ACI 0.35 cracked factor?

RE: High Rise Drift
2. You are allowed by ACI to multiply the standard inertia reduction factors by 1.43 (section R10.11.1) for service analysis.
