摘要:
从反映结构宏观损伤的非线性构形状态转移过程出发,建立了在位移控制加载机制下其状态概率、转移速率与屈服应变风险率函数之间的关系.通过力学与逻辑分析,导出了结构非线性构形状态概率演化方程.对于简单结构进行了解析求解,并据以研究了结构非线性随机演化的特征,讨论了稳定构形现象.从而为在概率意义上把握结构的非线性性能提供了可能.
Abstract:
Based on transition process of the nonlinear configuration state(NCS), which reflect the macroscopic structural damages, the relationship between the transition rate and the hazard function of the yielding strain is set up, and the probability evolution equations of the nonlinear configuration states are consequently established by combining mechanics analysis of the structure and logic analysis of the states. On the occasion of a simple structure the equations are analytical by solved, regulations of the nonlinear configuration state evolution are then discussed and the stable state is discovered. With the method proposed a possible means in understanding nonlinear performance of structures in the sense of probability is put forward.
