As for as I understand, OP in thread256-448758 was right that we shouldn't include the weight of soil above the footing if we check against net bearing capacity. However, everyone answered to include the weight of soil above footing which isn't exactly correct.
Could someone please answer this...
Per IBC 1806, we're allowed to presume the soil bearing capacity without a geotech report. However, Table 1806.2 only have value for bearing capacity and friction/cohesion for the 4 classes of soil. However, friction angle φ wasn't given, neither the soil unit weight. How do you guys get these...
EXACTLY. Given you input correct values(you understand how softwares work). Don't softwares do everything for us?
Yes, I'm serious, given I'm only 1.5 yoe, which I know nothing, hence, I asked the question. So, since the softwares are nowhere near that point of doing everything for you...
Other than super simple designs such as concrete beam(Mu/4d) and retaining walls level of simplicity. For more complicated stuff you studied in graduate program, did you actually use it? I feel like software will do everything for you. What do you think?
@Trenno
Sorry, I do understand that you meant load take/run down. But I'm not quite sure why you're doing load take down using concept. I'm sorry, not much experience here.
To put into column schedule or something similar? To get total load at the lowest level? Wouldn't RAM Structural System...

I used it when I was an intern at a facade consultant firm. It's more popular in Europe than US, but as they're trying to expand the US market, they got a team in US also. I think it's Philly-based. So, yea, it was a first-hand experience, but a short one.
Assuming I have all the reactions at the supports, is it possible to design the reinforcement for the column? As far as I know, we need reinforcement for column strips and middle strips. I don't have the load information.
I just gave RAM Concept API a try and I think I'm really close. I used the code from documentation to get the columns and walls reactions. Got every supports and compo results printed. However, the results are all 0s. Anybody has any clue?
Thank you!
Column strip is actually what I'm trying to to get to finally. This is also what I did and finally ending up with so many lines from one column at the center to all neighboring columns. That was when I started to think if I'm doing this thing correctly or just randomly drawing lines.
HA!! I tried this before, adopted from Thiessen Polygon Method from Hydrology measuring precipitation. However, I don't know the validity of the result so I stopped.
I'm not talking about simple buildings with typical bays. I was wondering how to get the correct load path for slab with columns placed in very random locations, no pattern.
Any resources/helps would be appreciated!
