(3) Which of the following is the most appropriate? (a) The allowable stress design (ASD) explicitly accounts for changes in load and changes in capacity by using separate factors (b) The load and resistance factor design (LRFD) explicitly accounts for changes in load and changes in capacity by using separate factors (c) ASD does not account for changes in loads during extreme events d) Designing a structure with ASD is always safer, although less economical, than designing it with LRFD (e) Both (b) and (c) 4) For structural steel and rebars, (a) high strength always results in high toughness (b) increasing strength often means lowering the ductility (c) high ductility often results in high toughness (d) brittleness is a desirable property (e) Only (b) and (c)Explanation / Answer
(3) Answer:- both (b) And (c)
The load and resistance factor design explicitly accounts for changes in load and changes in capacity by using separate factors. ASD does not account for changes in changes in loads in during extreme events.
(4) Answer:- (a) high strength always results in high toughness.
