Muller-Breslau principle states: the influence line for any response function (reaction, SF, BM) has a shape equal to:
Structural AnalysisInfluence LinesMEDIUM
Choose the correct answer
A
The bending moment diagram under unit load
B
The deflected shape of the structure when the constraint corresponding to the response is removed and a unit displacement/rotation is given
C
The elastic curve of the beam
D
The shear force diagram
Correct Answer
B. The deflected shape of the structure when the constraint corresponding to the response is removed and a unit displacement/rotation is given
Why is this the answer?
Muller-Breslau: IL shape = deflected shape of released structure. Use for qualitative ILs. For quantitative: place unit load and compute response.
