Yes, the two joists (point loads) at the ends of the girder do not contribute to shear or moment in the girder, so I ignore them. I didn’t provide enough detail in this exercise to show it, but those joists could either be supported on the girder or directly frame into the column. Obviously, if these frame right into the column, the girders don’t see these point loads at all.
You’re a great teacher. So well put together. Thank you Sir
You are welcome!
Great video, thanks a lot. Needed some more in depth explanation of this topic after reading about it in the reinforced concrete book.
Prof H. you are amazing!
Nice and simple explanation, thank you
Hi Prof, great explanation. Just to confirm that you are avoiding the two point loads just for convenience, correct?
