The Application of Multi-Node Cable Element

摘要

A non-linear finite element model of inclined cables,cables with non-leveled supports,in the large displacement and deformation fields is proposed for computing the dynamic response to wind loads which blow in arbitrary direction.The temperature-dependent elastoplastic behaviors of cables were taken into account in the nonlinear finite element model.This model was used for an extensive looping factor parameter study.A parametric super element model for cable passing through multiple pulleys is presented in this study for the static analysis of structures.The proposed formulation,which accounts for longitudinal inertia forces,allows to spot the circumstances when the simplified approach,adopting longitudinal mode condensation,becomes too crude.
