Generic Fixed Fixed with Triangular Load

I'm not sure what has come over me ... but I decided to crank out the making of the fixed-fixed beam with triangular load into a generic solution.

Baby! ...

Scary! Fun.

Updated the Superposition Examples Article ...


I update my article on some examples of the use of the Method of Superposition ... cool.


Generic Expression

... here is an article showing how we can take a specific solution and make the answer `generic'.

Deflections by Integration - Stat Det Beam

Okay ... here is the solution for the deflection of a statically determinate beam, simply supported, triangular load starting from zero at one (left) end and ending at the maximum at the other (right) end. The answer is in many textbooks (and manuals). In earlier articles we did this beam with fixed end conditions and with fixed ends with one end displaced.

In the solution our boundary conditions are ...

1. Known shear at one end.

Known Shear at the other end used as a check.

2. Known moment at one end.

Known Moment at other ends used as a check.

3. Zero displacement at one end.

4. Zero displacement at the other end.

Cool.

Diaphragm and Shear Wall info ...

hey, anyone following this blog ... here is a link to the APA design stuff on shear walls and diaphragms. Good stuff. APA is a big player ...
