| 摘 要： | 采用随机波浪谱和Miner线性疲劳累积损伤原理对轻型码头结构在波浪荷载和船舶撞击荷载共同作用下的疲劳可靠性进行研究。根据轻型码头结构变形大的特点,计算船舶撞击力时考虑了结构刚度对撞击力的影响,波浪荷载使用Morison方程计算,并以Airy波浪理论计算水质点速度。结果表明:波浪荷载和船舶撞击力对轻型码头结构的疲劳寿命均产生一定的影响,在进行疲劳可靠性分析时应考虑两种荷载的共同作用。

| Abstract: | The fatigue reliability of light-wharf structures which are affected by wave loads and ship impact forces is studied by wave spectrum analysis theory and the theory of linear cumulative damage.Based on the large displacements characteristics of light-wharf structures,we calculate the impact forces under consideration of the light-wharf's stiffness.The wave load is calculated by the Airy Wave Theory and the speed of water particles is calculated by the linear Morison Equation.The results show that the wave l... |
