摘要
推导了有阻尼与发生纵向共振时柱状结构的动力稳定计算公式 ,计算了水中平台动力失稳区间 ,探讨了阻尼与纵向共振的影响 。
An analyzing method to study the effect of damping and longitudinal resonance on the dynamic stability of columnar structures is discussed and formulas for investigate its instability zone are derived. Using the method, the instability domain is ascertained for an offshore platform subjected longitudinal loading. Finally, some useful results are obtained.
