Dynamic Stability of a Non-linear Continuous System Subjected to Vertical Seismic Excitation
Original language description
Easily deformable tall structures exposed to a strong vertical component of an earthquake excitation are endangered by auto-parametric resonance effects. This non-linear dynamic process in a post-critical regime caused heavy damage or collapses of many towers, bridges and other structures in the epicenter area. Vertical and horizontal response components are independent on the linear level. However their interaction takes place as a result of non-linear terms in post-critical regime. Two generally different types of post-critical regimes are presented: (i) post-critical state with possible recovery; (ii) exponentially rising horizontal response leading to a collapse. Special attention is paid to processes of transition from semi-trivial to post-critical state in the case of the time limited excitation period because it concerns the seismic processes. The solution method combining analytical and numerical approaches is developed and used. Its applicability and shortcomings are commented
