3 cards from this section. Quick, good the night before a test.
Define Fixed-End Moment in your own words.
Think of it as the moment caused by restriction at supports.
What is the first step in the moment distribution method?
Remember, it's based on the loads applied on the beam.
What does FEM stand for?
Remember the relation to fixed supports.
The moment distribution method allows for which of the following?
Think about its applications in structural engineering.
A continuous beam has fixed-end moments of +30 k-ft for one end and -60 k-ft for the other, subjected to a uniform load of 2 k/ft. Perform the moment distribution method and summarize your findings.
Start by calculating each fixed end before setting up your balance equations.
Discuss the implications of a joint experiencing translation while attempting moment distribution. What resulting errors might occur?
Consider how movement alters force distributions in structural members.
