Approximate Beam Analysis - The Art of Being Close Enough

This video is the first in a series on approximate structural analysis. Approximate analysis is valuable for checking results from an indeterminate or computer analysis. It is also very useful for multiple choice exams, such as the FE and PE exams - getting a quick answer that is close enough can eliminate incorrect solutions or even hone in on the correct answer.
This first video focuses on indeterminate beam analysis. An indeterminate system is converted to a determinate system by adding hinges at the inflection points (i.e., the locations of zero moment). Principles of locating inflection points are discussed, and two full examples problems are shown.

This video is awesome! It’s quick maths, but for beams?! And explained so neatly that I feel like I could use it to explain this stuff to anyone. And I was only a mechE student that took 1 class of civil!

Except for the units. Never even heard of a kip lol.

Thanks for the comment! Approximate analysis is really useful. A kip is a real unit, but probably only in the States. 1 kip = 1000 pounds, so I would guess the name comes from "kilo-pound". It's weird, but useful. That's just how we roll ;)

Sir, absolutely mind blowing. Your hinge method introduction is phenomenal. Please keep on posting great videos. I do have some few FEA uncleared questions. Is there any possible way to reach you?

I find your lecture is very interesting and easy to understand! Thank you for sharing!

Thanks sir from germany. I would be grateful to you if fürther videos of approximate analysis of frames are uploaded.
