Transcribed Image Text:Moment Envelopes
The following table contains the bending moments (kip-ft) at three points in a
beam. The beam is symmetric, so we only monitor the end, the quarter point, and
the middle.
Dead

6.84
Live
|-12.50
10.94
Earthquake

Apply the load combinations for dead, live, and earthquake. Then find the minimum
and maximum moment at each point. It is advisable to use a spreadsheet to speed
up your calculations and to correct errors more easily.
Once the calculation is finished, answer the two questions. Give all answers in
absolute value (no negative signs).
