Lol think LONG and HARD before you decide to do into civil. When I was in my senior year, I honestly didn't think too much about my choices and just chose civil due to promising job prospects and pleasing my parents. I had the grades and aptitude to do it so I thought, why not? I regret my decision with increasing intensity everyday (2nd yr now). My 2nd choice would've been comp sci or software eng and I honestly wish I would've done that. Fact is, I knew next to nothing about the field when I applied other than the superfluous and one-dimensional duty of designing "bridges and stuff".

Fact is, civil engineering is probably the most broad of all engineering disciplines. You can do anything from traffic analysis/design, municipal infrastructure, construction management, materials eng (testing, specifications, concrete/asphalt mix designs, etc.), structural design, structural detailing/erection, demolition, geotechnical, water resources management/infrastructure design, cadestral surveying (geomatics), etc.).

That said, not a single course I've taken has even remotely sparked my interest besides my physics and math courses (and we've touched on most of what I mentioned above). A lot of structural science boils down to just statics and mechanics of materials. You essentially always want to keep your structure in static equilibrium (sum of all forces and moments in all directions = 0). Mechanics is the study of the deformations of materials when subjected to loads (twisting, contracting, expanding, bending, shearing, etc.). Essentially everything here is derived from Hooke's law and basic geometric principles with some calc involved (well that applies to anytime you deal with differential elements).

Structural design isn't what it seems like. In fact, I don't see how anyone can do it without wanting to blow their fucking brains out. Most of it boils down to using the fucking codes and referencing material standards. Material standards give the factored resistances under compression, tension, etc. However, a lot of these relationships are empirically derived, so they're nonsensical at face value and have a plethora of fucking coefficients and specific clauses on different cases that you have to sort through. Best part is, these standards and codes change every 5 years or so, so you get to rememorize all this bullshit again. Top that off, these books are like $500 a piece. Don't like looking stuff up tables? Get used it, Civil is enamored with it. Structural design is basically trial and error. Get your dead/snow/wind loads and size your members. Big fucking whoop. Lateral loads from wind/earthquake are a bit more complicated but they're many simplified published methods of designing for that (braced/moment frames, shear walls, pretty much all it boils down to). Steel is the material that generally is least heavy with the clauses/coefficients because it's a synthetic material. It's engineered to be prismatic and isotropic so it aligns closer to the assumptions made under many of mechanical principles. Hence why many engineers prefer designing with steel and timber is stuffed away like cat piss. Reinforced concrete > all though.

But let's say you're a smart guy. You think you know your mathematical/scientific relationships well enough that you want to do something different. You don't want to do the tired and true. LOL NOPE. Too vastly complex to even bother trying. Too much risk involved. Psh, better just to go back to the god damn tables and formulas spoon fed to you. A lot of ppl engi degree is hard, nope, it's basically plug and chug. Most kids could give any less of fk where the formulas they're using came from. Don't get me wrong, structural analysis can get very mathematically rigorous and complex when analyzing indeterminacies (most structures are indeterminate) but you will hardly touch on that fun stuff in your Bachelors. The most dynamic analysis you'll do is related to vibration/seismic design. But you'll hardly touch this unless you go for a masters/PhD.

Geotechnical design is even worse. Man I really love taking a clay sample and seeing it consolidate 3mm after 2 hours. Love it.

Municipal design is just extremely tedious and monotonous. Sizing pipes for fireflow and ensuring you have adequate pump head to distribute water along the entire system without falling below min or above max requirements. Again, following your published municipal code. Earth shattering stuff this is -__-.
