Eigenvalue analysis approach to random periodic parameter-excited stability : application to a stay cable
Z. G. Ying,Yiqing Ni +1 more
TL;DR: In this paper, a direct eigenvalue analysis approach to solving the stability problem of randomly and periodically parametrically excited linear systems is developed based on the response moment stability, which is a generalization of the one proposed in this paper.

Seismic Response Analysis of Multi-Span Cable-Stayed Bridge
TL;DR: Based on the dynamic characteristics analysis results of a precise three-dimensional finite element model, the earthquake responses of the bridge are analyzed in this article, where the influences of cable local modes and stabilizing cables on the seismic response are investigated by using different mode combinations and different models.
