Steel design and examples in construction

I've enjoyed taking both construction engineering and steel design courses this semester, learning how steel is made and used in structures, and then how the members are chosen as well as the shape and connection design/method. 

In construction engineering class, I learned about common construction methods, terminology, and materials used, basically getting a very solid general understanding of everything that goes into construction. During a Revit project, I saw the big picture of steel beams and a steel deck making up the frame of a concept high school, and chose the correct size and dimensions from directions. 

And then in steel design class, we went over all the calculations and aspects you need to acknowledge to follow the steel code in order to design all the steel members used in construction, including steel beams like used in the concept high school above. We design members with constraints shown in the next image, with actual cases maybe looking something like the last picture:
