@JoshPluSE this is invaluable information for me, thank you! I will have to play around with this technique and understand it more before implementing it, but this concept of lumping mass in additional BLCs is certainly not something I would have been able to discover on my own.
Hello, I'm hoping to get some help with a particular problem for some models I've encountered when using dynamic (seismic) analysis. The problem is when have I have no single mode with a particularly large mass participation in the x or z directions. I know that generally, you want to acheive...
Sorry but I'm not very familiar with MWFRS and C&C because we don't use that precise a methodology in Canadian Code. I would assume since you are resolving loads to your foundation, you would use the MWFRS wind calcs because your columns would be part of your MWFRS. Personally, I would just...
I believe your confusion is coming from what you are trying to find. In your example, you are trying to determine the forces acting on a sloped member. Dead load and snow load always act vertically, but you need to resolve your forces to act normal and parallel to your member being analyzed to...
I am not super familiar with American codes, but Canadian is similar. You have 4 wind load combinations to check (technically 8, but 4 can be omitted due to judgement):
0.9 DL + 1.0 WL (0°, Case A)
0.9 DL + 1.0 WL (0°, Case B)
1.2 DL + 1.0 WL (180°, Case A)
1.2 DL + 1.0 WL (180°, Case B)
You...
