Abstract
In this paper a spline finite element model is derived to
analyze dynamic stability of cables and cable structures. The
total form of strain is adopted in computation to ensure the
convergence of iterations under large displacement
increments. The nonlinear stability of elastic inclined cables
under cyclically loading is investigated. The effects of the
concentrated and distributed loads on cables are analyzed.
The reactions of excited cables are studied. Numerical
examples are conducted to study the dynamic behaviors of
simple structure supported by the cables in parametric
resonance zones. It shows that the parametric instability of
cables must be carefully dealt with in engineering.
