If you start too soon, you will wear out the F5 key and it may not be there for you when you need it.

So you measured the table with the ruler you were going to sketch with! The table we had was also like that. There are no standards or specifications for exam tables. Each site has its furniture meant for their core operations. Years ago, when I took the PE, I had to sit on a chair meant for...

Rho and Omega are applied in two different contexts. For inertial forces calculated per eq. 12.10-1, Rho is 1. For transfer forces, Rho is the same as for the structure. It can be 1 or 1.3. Ev is an inertial force, Rho is 1. Why some may mistakenly apply 1.3 making a difference. I think why...

Was it meant to say the intent might be not to use omega for both components? This kind of thing happens to me when keying in is slower than the thought progression.

I think I have seen that. Even though it is shown as say 3 ( Eh + Ev) in the solution for the OMF example, by mistake IMHO, the flow of numbers does not include Ev. I think that is one for errata in that book. Rho or Omega are not applied to Ev. The two combos with E/Qe will still be with...

In their equations, ACI uses E; ASCE uses Qe. Why they cannot even rationalize notations to make it easier for the codes user is something. Let us leave that aside. The difference between anchors and the frame members is that if overstrength is applied to both H and V by mistake, we end up with...

My understanding is this. Ev is not affected by Rho or Omega. Only Eh = RhoQe or as in this case maximum Eh i.e. Emh= OmegaQe. Qe are forces associated only with the horizontal component of the earthquake load. Rho or Omega is applied only to effects from the horizontal components in the load...

Yeah, it will mask the pain. More seriously, with all the strains of COVID-19 floating around, UK, South African, Brazilian, who knows what else, being vaccinated may go only so far. Prudence is the better part of valor. Stay safe and put your best foot forward.

@organix, these things happen. They will not make or break the exam and can wait. This is not the only item I have a beef with (actually I am a veggie guy!) in some code/specifications arena. Take it easy, good luck at the exam.

I just wanted say this until I get back after the exam. I looked at the SEAOC example again. Sure, the definition of a bay is given for shear walls in b. in terms of height to length ratio. Are moment frames also defined as shear walls? May be but it defies my logic as the failure mechanisms...

Correction: “They cause unbalanced lateral force in the roof beam....”. Meant to say unbalanced vertical force.

If only you had read it dispassionately you would have realized that was exactly what I had said. Your earlier post ran thus: Where? If you're referring to 12.3.4.2.b, it is completely irrelevant if you meet 12.3.4.2.a. (underline mine). Your reference was to a. only there. My focus was on a...

Please read the second sentence in 12.3.4.2 “For other structures...shall be equal to 1.3 unless one of the following two conditions is met.....”. a. and b. are the two conditions. My post was not saying a. did not apply to one story. It applies to any number of stories. Each story ....more...

TG, I hear you loud and clear. I can see them going for more CFS in time, simply for the reason you mentioned. But until more use is made of CFS by the industry and examinees would be expected to show proficiency in CFS to protect public safety, it may not happen in time for us. I would make...

The second paragraph answers this. Why data collection was suggested. To each his or her own.

lateral wind loads (I believe wind loads applied to the steel beam in the minor axis direction).).....” Please clarify this for my understanding. Is the beam web upright or is is flat? Is the wind load an uplift or is it horizontal? Could not wind pressure applied in the direction of the...

I am not trying to convince anyone but I am a contrarian. Here is how I view my original interest in floating the thought. The essays are the Achilles heel. If those who did not pass are polled, I think it would be borne out that more examinees performed “better” in the MCQ than in the essays...

For each day/date it looks if one is taking both days.

This is a good exercise in code interpretation. 12.3.4.2.a. is even a non-starter because this is a single story, 100% of base shear is always shared regardless of walls layout. So a. is the one that is “completely irrelevant“, not the other way around.

Watch out for it tomorrow morning. Good luck at the exam.
