I have been stressing about structural information the whole time I have been studying for PPD.
I finally found what I think is useful and easy enough to work through to help promote understanding of all the structural concepts in the PPI ARE5.0 Review Manual.
I am pretty sure the ARE will not get into intense maximum moment calculations and the like, but I was able to follow through chapters 34 and 35 and take in the information to FINALLY be confident in my understanding of structural concepts.
UNIFORM LOAD is calculated as the SUM of the Force ACTING @ CENTER of the Uniform Load
MAXIMUM Moment occurs where SHEAR crosses the zero line
In a SHEAR diagram:
UPWARD FORCE = Positive / DOWNWARD FORCE = Negative
SLOPED LINES will be PARABOLIC on a Moment Diagram
HORIZONTAL LINES will be straight sloped lines on a Moment Diagram
If forces cause a beam to bend DOWNWARD they are POSITIVE MOMENT FORCES and if the beam would bend UPWARD that beam is experiences NEGATIVE MOMENT FORCE
These were some things I wish I would have had a better understanding of the first time I took PPD.
