Inter-story drift ratio Vs. overall story drift ratio
Inter-story drift ratio Vs. overall story drift ratio
(OP)
As we al know, the inter-story drift ratio is an important coefficient in the high-rise building design. However, is the Maximum displacement / building height considered as a more important index in US design? Say, satisfy the wind load to 1/400 x H.






RE: Inter-story drift ratio Vs. overall story drift ratio
You have to check them both.
However, if you design each story for an interstory drift of H/400, your total drift will be less than or equal to H/400, though if you design the total building for H/400, it doesn't mean each story deflection is less than H/400.
