CVEN 345 – Structural Analysis – 2020c

Posted on July 22, 2021 by Abigail Stason

Lectures and Notes

The Lectures are on Zoom

You will need Adobe Reader to view the Class Notes files. The Notes files can be viewed by left-clicking on them or by downloading them to your computer by right-clicking and then “Save Target As.”

Note that the web links below may be pre-listed, but will not be hot until after class when we generate the notes and videos and I can get them posted.  If I get behind, and you are ready to use them, please email me at Lowery@tamu.edu to remind me.

This year’s notes are available below.   The videos to go with the notes are available on Zoom, as listed below.

Lecture videos – You may have to cut and paste some of these long URLs
Also be careful if it does indeed need a password.

Class 8

Lecture 8 – Notes  Tuesday 9/15/2020

Lecture starts 11 minutes into the video.  Full example of taking a statically indetermnate truss and solving for everything necessary to get the redundant reactions.  Also, determining the energy stored in beams and frames for soution of their redundant reactions.

Class 9

Lecture 9 – Notes Thursday 9/17/2020

Lecture starts 16:15 into the video.  Short review if how to recognize a truss is statically indeterminate, how to turn it into a primary statically determinate truss for analysis by flexibility methods.  Complete previous work on the same truss to solve for deflection of primary structure at point of removed redundant reaction.  Solve for redundant reaction on truss.

Next, solve for the redundant reaction on a one-degree statically indeterminate beam.  Zoom locked up on us then but fortunately kept recording so we kept discussing the solution.  We will start here next lecture.
