Hello,
I am trying to use notional loads(ASCE7-05 Section 11.7.2) as seismic load that's why the building is assigned to Seismic Design Category A.
And I will use direct analysis method when designing the building as well.
I wonder there is no problem or not if I use notional load function in STAAD as both seismic load and direct analysis at once.
What I want to wondering is in detail as below:
For example, when using combination : 1.2D+L+E (D = dead load, L = live load, E = seismic load),
then, input a Notional load in STAAD = 1.2D * (0.002 + 0.01/1.2) + 1.6L * 0.002(E = 0.01D)
(0.002 = notional load factor in direct analysis, 0.01 = equivalent later loads in Seismic Design Category A)
