Influence Lines and Moving Loads - Intro to Structural Analysis

This video defines the concept of an influence line for a moving loads across a structure. This is a very useful technique in bridge engineering.
If you want to follow along with the statics (which are skipped in interest of brevity), the full calculations can be downloaded here:

An influence line plots a specific action (for example, a reaction force or the shear or moment at a specific point) for a unit load at position x, moving along the structure. These can be used to find the extreme loading events for a specific demand.
This video covers how to solve for an influence line using statics. The Muller-Breslau principle, which can be used to find influence lines using geometry, is described here: • Muller-Breslau Princip...
What can you do with influence lines? Check out this video on how to use influence lines to position live load and get the worst case demands (i.e., to find the design envelopes): • Design Envelopes for W...

I was looking at every video and my old textbooks and I couldnt wrap my head around this... I watch this vid and like half way through it clicked for me. Thank you so much, Prof.

[@StructuresProfH]

Glad it helped!

[@offthegridengineer2198]

Extremely helpful, as always! Thank you

[@ce.emir7]

amazing teaching,thank you verry verry and verry much🙏🏻

[@StructuresProfH]

You are very welcome!

In principle do we come up with segments using hinges. I have a continuous beam with no hinges

[@zhilyaismael8435]

thank you dear prof . could you please cane you give me some idea how it's come in in exam?

[@chidubemoleka8729]

I have some problems, I don't know if you could help me

[@chidubemoleka8729]

Some structural engineering problems that I need the solution

[@LSZ71]

maybe go through the statics real fast while you do all of this. might help people

[@StructuresProfH]

Good idea. Sorry it took me so long to get to this. This calculation sheet will lead you through the entire problem (all statics shown). drive.google.com/file/d/19rEG9XjrJwqRhD5Wc33PsTW7wzz9sDZs/view?usp=share_link

[@luziya7486]

Prof. This is great. What app did you use to write the solution? I’m studying structural engineering and we will be submitting our assignments virtually so I need an online too I can use
