摘要
本文讨论了综合模态屈曲理论。该理论同时考虑多个模态及其相互作用对结构屈曲的影响,能解释以往的屈曲理论所不能解释的屈曲现象,对实践有重要的指导意义。
The theory of interactive buckling gives a new analytic model to describe nonlinear elastic buckling of structures. Multiple buckling modes and their interaction are considered. It can explain the phenomena which can't be explained by other buckling theories. Results of the theoretically predicted and experimetally observed collapse loads are in good agreement.
