So, judging from the NCEES exam outline as well as both the 2008 NCEES sample exam and the 2011 NCEES sample exams - we are pretty much guaranteed a question on Dead, Live and Wind loads. However, I do not see any info on this topic in either Goswami or the CERM.
The 2008 question asks for which load combination causes maximum uplift on a footing, and the answer is wind + dead load. Live load is discounted (I assume) because it transfers a force down onto the footing. Dead load does too, but it is counted (again I assume) because it dead load is always counted.
The 2011 question is similar, but this time the answer is wind + live + dead. Live load is counted this time because it is cantilevered to the footing and doesn't transfer its force straight through it.
These questions seem pretty easy - and I don't want to throw away an easy point. Anyone know of a free website where a little more info on load combinations can be learned. Perhaps a few more example questions? Alternatively, if anyone knows of any 'tricks' these problems typically might have and would care to share that'd be great too.
