TEST CASES
Figure 1 illustrates the layout of the cables and the deformed shapes due to the static loads. Figure 2, Figure 3 and Figure 4 respectively show tension, stress and strain along the length of the cables for the different load cases. Figure 5, Figure 6 and Figure 7 describe the first three natural mode shapes of the middle span. Static and dynamic deformed shapes have been amplified by a factor 5.
