(CLO 5 Students are able to apply the concept of equilibrium in calculating and plotting influence
lines of support reaction and internal forces of moment and shear in a statically determinate structure
of a Gerber beam, as described in Figure 1.
Calculate and draw the influence lines:
a. Draw separately the main beams (balok induk) from the secondary beam (balok anak). Put the
secondary beam above the main beams.
b. Calculate and draw the influence lines of Support Reaction MD, VB, and VC.
c. Calculate and draw the influence lines of shear and bending moment of section I and II (see
Figure 1)
d. If a uniformly distributed load (10 kN/m within 2 meter of length) moves along those beams, find
the maximum Support reaction VB and VC.
