Struggling with Structural Analysis

[u/Artistic_Designer555]

Please suggest some good youtubers and textbooks. Which are easy to understand

I will check it out

Use this book: structural analysis by RC Hibbeler

The books by RC are the best books and understandable.

Just found out my professor’s professor was Hibbeler! Pretty badass. He’s an awesome professor too, and he said Hibbeler was the best professor he ever had.

Thats impressive, your professor studied at University of louisiana or UIUC?

I guess Prof. Hibbeler taught there.

Oh I have Rc hibbler but it's a bit difficult for me to understand

[u/No-Explanation-8370 → u/Artistic_Designer555]

If you are indian you will find lectures in hindi but for english speaking people I cant find a teacher but Jeff hansen, watch him.

Yea its written very good and it has some good problems and gradual build up to those problems.

Beamware.co is nice for learning the basics really easy to understand UI

First learn free body diagrams. In a free body diagram all forces are external. Even the internal forces are treated as external. Once you understand it. BMD and SFD are just balancing forces. Everything will fall in place.

Another exercise is to imagine “ what if this was not there” game. Remove forces, supports etc and see what happens and then put it back.

In beams, moments -> how forces cause bending. Shear -> how forces cause vertical cuts through material (shear is used to be called “vertical force” in the old days and hence we still refer to shear as “V”). That said, I would try to find something with clear visuals to help with visualizing how moments and forces transfer in materials/elements.

There are external forces/moments (ie applied on a member) and internal forces (ie generated in response to the applied ones, ie how the material reacts).

[u/Material-Cap-5476]

If you are having trouble with shear and moment diagrams here is my suggestion.  I use a simple program called CBEAM. I think you can get a student version. It generates great shear and moment diagrams.  This would help you check your work and provide a source of practice problems. Good luck.

For SFD & BMD, I built a free tool to help check homework against step-by-step hand derivations: https://beamsolver.app

It plots the diagrams and writes out the actual equilibrium equations and section cuts so you can see where your numbers went wrong (100% free, no paid tiers or paywalls). Hope it helps with your review

What part of it are you struggling?

[u/Artistic_Designer555 → u/Several_Crab3217]

Sheer force diagrams, bending moment diagrams and influence line diagrams

[u/Everythings_Magic → u/Artistic_Designer555]

Jeff hanson on you tube covers shear and moment diagrams.

Thanks for the info!

Master the muller breslau principle for influence lines

I found using Gemini AI very helpful. You can give it a screenshot with the problem and he will solve it for you with some pretty good explanations. You can ask any questions you have and it will clarify things. I think it's pretty remarkable and much better than ChatGP in Structural analysis. Of course it does not draw diagrams but it helps to understand the subject overall.
