Problem 104 is the first error I've found (only done 4 problems so far), and they forget to include the Cu factor in determining the period. T=Cu*Ta. They use Ta in the problem, but the answer would most closely match A anyways...
FYI.

Also on problem 102, maybe someone can direct me as to why the building has an occupancy category of I (low hazard). It's a warehouse. They don't seem to say anything more than that.

The problem says that it is a "minor storage facility", which is specifically listed in Occupancy Category I in ASCE 7-05 (Table 1-1).

I suppose I'm not accustomed to looking at the occupancy categories in ASCE 7, moreso in IBC 2006/2009.

No problem. Gotta love the strict adherence to the code...makes this process so much more fun.

It's my understanding that T=Cu*Ta is only the upper limit of T, not the fundamental period itself. Without performing an analysis to find T, the only option we have in that problem is using Ta as T, which is allowed per ASCE 12.8.2:Problem 104 is the first error I've found (only done 4 problems so far), and they forget to include the Cu factor in determining the period.

Let me know if I'm missing something here...As an alternative to performing an analysis to determine the fundamental period, T, it is permitted to use the approximate building period, Ta.
Well, if we are to be specific, Ta="Approximate" fundamental period, and the problem statement should have been more clear in my opinion.It's my understanding that T=Cu*Ta is only the upper limit of T, not the fundamental period itself.

The value for Tmax is really for the seismic force determination via Modal or Seismic Response. (Note: both modal & Seismic response can use eignsolution & SRSS methods.)I am trying to figure out the purpose of the T max. Is it for the Cs(max) equation or if you are to use an eigensolution / SRSS? Any comments would help me out. Thanks!
