Talk nerdy to me...
You have some excellent points and I certainly appreciate the input from an academic perspective. I do have a few items I would like to add though.It’s my opinion that it’s taking longer and longer for firms to train recent graduates, because in general engineering professors don’t have the ability to or are too arrogant/lazy to teach well-prepped courses. In turn, students are not learning how to think on their own. I’ll just use structural analysis as an example. Traditionally, most professors will follow the chapters outlined in the Hibbler book, and all homework and exam questions will come from that book. The students will most likely torrent the solution manual for the book, and the only thing that’s been learned is how to copy. What the professors should be doing is calling up a structural firm, asking for a set of basic plans, and telling students to draw the shear and moment diagram for the beam at grid line A between 1-3 accounting for material weights and live load. This requires the student to actually think about how to calculate loads, and shows them that a beam is not a rectangular block that sits on top of a triangle and a circle. Professors don’t do this because it would actually require them to solve the problems themselves, plus they might get a question that actually requires them to look at something other than a textbook to answer it. I know this is true, because during the very first class of my structural capstone class, I give the students a set of structural plans and tell them to calculate the unfactored loads that would be transferred to a footing. I get looks like I’m speaking in a foreign language and they need the Rosetta Stone to do the calculations. This is just one example of how professors lack in basic teaching skills. The other common issue in engineering is professors cram a ridiculous amount of material into a single course. I wish professors would realize that fullly understanding a little is better than not knowing much about a lot. My favorite example of this is the steel professor at my college. For his class he covers tension, bending, shear, compression, torsion, bearing and slip critical connections including eccentricity, welds, 1st and 2nd order frame stability analysis, and base plate design. That sounds great until the students get to my advanced design class and can’t tell me whether a bolt is in shear or tension, or how forces are transferred in a bearing connection.
In addition to this, professors don’t ask students to draft anymore which is beyond ridiculous, so again students get no exposure to how an actual building fits together. Almost everyone of my homeworks requires students to draft a beam or connection they’ve designed from a set of plans, and it pisses me off that my other colleagues won’t do the same. Another underlying issue that I don’t think industry is as aware of are the use of adjuncts to teach fundamental classes. With academia trying to be as cheap as humanly possible, more and more temporary teaching positions are used to cover classes like statics, strength of materials, etc. The interview process for some of these positions goes like this, “Oh, you have a PhD and took statics and are willing to work for wages you couldn’t live on, congratulations, you’re hired”. Then what happens is you get someone that either a) hasn’t actually used statics in the 21st century, b) is some cryptic old person with one foot in the grave that is senile, or c) is a international professor that follows a textbook like cooking instructions from a recipe book with no variation, and doesn’t actually understand statics beyond the class problems. When this happens students come out of the course more confused than when they went in, and the effects carry over from course to course until graduation. I actually saw one college have an environmental engineering professor teach statics, and another college had a construction management professor teach strength of materials. Finally, one of the most critical problems is professors aren’t willing to raise the standard that students should meet. To elaborate, professors don’t fail as many students as they should, and they’re not making students responsible for basic skills such as penmanship and drafting. A lot of this also has to do with the tenure process, where, if you bring in a million dollar grant you could essentially take a dump in the middle of your classroom and still get tenure.
What I’m getting at is it shouldn’t be difficult or time-consuming to teach a recent graduate masonry design, if the graduates actually knew how to critically think.
1) I didn't necessarily mean an MS is needed to take the PE. I meant a young structural engineer is not adequately trained and cannot demonstrate a minimal competency for an engineering license without the addition of more classes than are currently taught at a BS level (semantics, I know). This may not be the case with all disciplines but from my perspective, the Civil Structural exam personifies many of the topics you've discussed. First and foremost, the exam has nothing to do with putting a building together, but more about solving simple statics, indeterminate, materials, and design problems. It brings to mind exactly what you described as "students not knowing a beam is something more than a line on a circle and a triangle." I don't recall seeing any questions concerning complex system design on this exam.
2) I think an accelerated 5 year MS would be an excellent compromise. I don't think students should have to toil away forever to pursue their career but I do expect ALL of our hires to have some understanding of the 4 main construction materials (wood, steel, concrete, and masonry). Though it could be argued that masonry is similar to concrete on the LRFD design side, new employees are going to struggle and frustrate me without an in depth understanding of at least concrete. More often than not, BS grads barely understand how to design concrete columns due to the interaction of axial and bending loads.
3) I would argue that finite element analysis understanding is imperative for 2 reasons. First, I do not want to be teaching new hires finite element methods. Second, I don't want my engineers using finite element programs without understanding how they work.
4) The steel professor probably needs to split his material across 2 classes. Not only could he cover the valuable material you described, but he could add even more like gusset connections and special seismic detailing. This would be perfect for the 5 year MS program. It would also prepare grads for the SE exam. I was poorly prepared for special seismic detailing due to performing all of my engineering on the east coast out of high seismic areas.
5) Wood design is the most different from the other materials due to its anisotropic properties. This is not something I want to spend my time teaching new hires either. I already have my hands full with metal studs, aluminum, and more in depth design with the common materials.
6) I agree that students are sorely lacking in critical thinking skills. I would disagree this is solely academia's fault. To some extent it may be due to the fact that academia does not cull enough students, but my take on this is generational. I believe the lack of critical thinking skills is largely due to a fear of failure. Young college grads are afraid to try anything they don't fully understand due to their sheltered upbringing and parents not instilling basic societal knowledge into their children. In other words, "It's OK to fail as long as you learn from it and not everyone gets a trophy."
Again, I appreciate the feedback and rather than continue to post my gripes I am going to list off what I believe to be the most important classes to young structural grads (obviously beyond the math courses required to understand these concepts).
1)Statics
2)Mechanics of materials - basic indeterminate structures
3)Structural Analysis - indeterminate structural analysis methods such as moment distribution, integration method, Bernoulli and Timoshenko beam theory, etc...
3)Wood/timber design - incorporating shear walls, connections, lateral torsional buckling, and basic column design
4)Steel design - incorporating all of the items mentioned in your post and adding special seismic detailing at a minimum
5)Concrete design - incorporating shear walls, beams, T-beams, torsion, shear, punching shear, slabs, interactions at column/beam joints, and special seismic detailing.
6)Masonry design - basic column, pilaster, beam, and shear design while incorporating special seismic detailing.
7)Finite element methods - at least a basic understanding of how stiffness matrices are constructed and solved given the different end restraints.
These items would produce a perfect hire for me right out of college but sadly much less than half of this knowledge is present in graduates with a BS degree and many with an MS lack a significant portion of these qualities. Given the current restrictions upon academia, I don't see how the above items could be covered in a satisfactory manner without the addition of at least a 5 year accelerated MS program.
