ASD
WSD
What is the updated version of WSD for steel design only?
LRFD
USD
ASD
WSD
The factors in LRFD Load Combinations are based on what?

Experience
NSCP author
The following Load Combination is under what?
1.4D + 1.7L
WSD
USD
LRFD
Strength Design
What is the difference between old-fashioned USD (Ultimate Strength Design) and "Strength Design" (most popular term nowadays)
They differ in terms only
USD is based on elastic theory while strength design is based on ultimate strength
Load Combination load factors for USD are different from Strength Design load factors
USD uses ASD Load Combinations while Strength Design uses LRFD Load Combinations
Among the following, what is considered as a load combination of "Strength Design"?
D + L
1.4D + 1.7L
1.2D + 1.6L
D + 1.3L
Why does the NSCP include ASD/WSD approach instead of totally removing it? Aside from the reason that we are transitioning to LRFD, give one reason.
WSD/ASD is being used for capacity checks.
Civil engineers are using WSD/ASD for serviceability checks for the reinforced concrete structures.
ASD/WSD serves as a remembrance of the structural code history.
ASD/WSD can determine the capacity of some structures that LRFD cannot.
What is the load-combinations-approach for Strength Design?
ASD
WSD
USD
LRFD
What does the elastic theory imply from the Working Stress Design approach?
The maximum steel capacity is the point of rupture.
The maximum steel capacity is the ultimate tensile strength.
The maximum steel capacity is the yielding strength (fy).
None of the above
