Re: Overturning check

[Subject Prev][Subject Next][Thread Prev][Thread Next]
When wind controls, ASCE 7-95 section 2.4.4 states that "buildings and other
structures shall be designed so that the overturning moment due to lateral
forces (wind or flood) acting singly or in combination does not exceed
two-thirds of the dead load stabilizing moment". The safety factor then is
3/2 = 1.5.
