I agree with most of the previous comments. I passed the exam last year, so I didnt have to deal with the code switch.. but if I had, im sure the lateral would have been tougher.
None of the states around me have adopted the 2018 ibc yet.

I took lateral yesterday. I can think of a mistake or two that I made (i realized on my ride home that I really neglected some stuff on the wood one ), but, in hindsight I felt the PM portion was fair and I didnt pick up on any exam errors. I'm sure I'll be retaking it because I'm pretty sure my...
I feel the 50%>33% is meaningful. The way I see it,
Grid 1 and 2 each provide 50% of the story strength (flexible diaphragm).
If you remove the frame at grid 1 there is a reduction in story strength of 50%, which is greater than 33%. So P is 1.3.
Im probably late on this..
The way I read the solution is that its stating that the percentage of the lateral load resisted by the frame on grid 1 is 50%. This is greater than 33% (hence the 50%>33%) so the redundancy factor is 1.3
Thank you both for your responses. I've decided that I'm going to focus on Alan William's Seismic and Wind Forces, SEOAC Volume 1, and David Connor's bridge book. I will try to review SEOAC Volumes 2-4 if I have enough time.
Happy New Year!
I would be interested in joining a study group. I passed the vertical this fall by studying alone, but I feel I could use some help setting up a study plan for the lateral portion.
Has anyone ever used the "California Civil Seismic Building Design, 12th Edition" to study for the SE lateral exam? I recently passed the vertical and trying to get organized for the lateral.
If you haven't used this book, could you recommend a book for a structural engineer with little to no...
