NCARB Sample Multiple Choice Questions

[j2004]

Can anyone explain the answers for #17, 23, 24, 29 from the NCARB Sample Multiple Choice Questions. Or know where I can find the source to these solutions for further reading?

Thanks!

#17 Find a Means Cost Data book and go through the estimating exercises for each of the materials listed or call a contractor to help you.

#23 I am not sure of the best source. The two outside columns will take 50% of the overturning moment while the single interior column takes up the other 50%.

#24 This buried in FEMA. I stating this out of memory so I may be wrong with the figures, but it is there. Base isolation loses its effectiveness after a 2.0 second period, which translates to a 20 story building. Therefore C & D are out. A one-story does not need isolation since it has no stories above to wiggle. This leaves a 4-story building as the answer.

#29 Its NCARBland. Expect it to be about architects. Since the architect is usually the prime designer, they are the primary legal responsibility. There are too many scenarios to state this is a good question/answer. It should not be on the sample, because too little information is given. It could be the contractor, engineer, or other. It also does not face the reality that the one with the deepest pockets is often the prime legal responsibility, but its NCARBland and not reality.

Hope this helps.

17. Gypsum shaftwall is clearly the least expensive choice.
29. Prime contract = primary legal responsibility.

RE #24:
I couldn't locate it in FEMA, but from "Base Isolation Of Structures"
...the height and period range of the prototypes tested have been restricted to low to mid rise buildings with relatively short periods for their height. This is the type building that is most likely to be a candidate for base isolation."
They don't articulate why.
here is the link.
