ASCE 7-10 ASD Vs. LRFD

 ASCE 7-10 revised load factors for wind in allowable stress design (ASD) and load and resistance factor design (LRFD) load combinations.

Design velocity pressure for ASD and LRFD are:

ASD: qz10_ASD = (0.6)(qz10) (Eq. 5)

LRFD: qz10_LRFD = (1.0)(qz10) (Eq.6)

where:

0.6 = ASCE 7-10 ASD load factor for wind

1.0 = ASCE 7-10 LRFD load factor for wind
