Textbook Question
Chapter 5, Problem 5.2QPP
Why would the AASHTO separate structural dead loads from wearing surface dead loads and use different load factors for each, whereas ASCE 7 has only one category for dead loads?

In accordance to NSCP 2010, the calculation of the required strength U shall be at least equal to the effects of
the factored loads below where the effects of one or more loads not acting simultaneously shall be investigated:
U=14 (D)
U=12 (D) +1.6 (L) + 0.8 (W)
U=12 (D) +1.0 (E) +1.0 (L)
U=0.9 D+1.6 W
Results from elastic analysis of a concrete beam yields the following values of un-factored (service) moments:
Dead load moment = 50 kN-m
Live load moment = 80 kN-m
Wind load moment = 60 kN-m
Earthquake load moment = 100 kN-m
Determine the value of the factored moment (kN-m) that will be used in designing the member.
