Fixed end moments (FEM) for a beam of span L with central concentrated load W:
Structural AnalysisMoment Distribution MethodEASY
Choose the correct answer
A
FEM = WL/8 at each end (opposite signs)
B
FEM = WL/12
C
FEM = WL/6
D
FEM = 5WL/48
Correct Answer
A. FEM = WL/8 at each end (opposite signs)
Why is this the answer?
FEM for central load W: at near end = +WL/8, far end = −WL/8. For UDL w: FEM = ±wL²/12. Sign convention: sagging positive.
