Muller-Breslau Principle for Influence Lines - Intro to Structural Analysis

The Muller-Breslau Principle gives us an easy, geometric way of constructing influence lines. This video covers how to solve for an influence line using Muller-Breslau, then lays out some rules to follow that will help you always draw the right shape for determinate and indeterminate systems. Finally, the video concludes with an example of how to use geometry to find not only the shape, but also the values of influence lines using geometry.

A previous video covers how to solve for an influence line using statics:    • Influence Lines and Moving Loads - In...  

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 Worst-Case Deman...
