Civil Engineering MCQAE Level Civil Engineering
A fixed beam of span L carries a central concentrated load W. The fixed-end moment at each support is:
Structural AnalysisFixed Beam Central LoadMEDIUM
Choose the correct answer
A
WL/4
B
WL/6
C
WL/8
D
WL/12
Correct Answer
C. WL/8
Why is this the answer?
For a fixed beam with central point load W, FEM at each end = WL/8 (hogging). The midspan BM under the load = WL/8 (sagging), equal to the fixed-end moments.
