摘要
利用“拟载荷“方法求解出了结构动力响应的灵敏度公式 ,进而又推导出了可靠性指标的灵敏度公式 ,从而得出了动应力可靠性约束和动位移可靠性约束的灵敏度公式。
Analysis of dynamic sensitivity is a difficult problem in the design of structural dynamic optimization. In this paper, the structural dynamic response sensitivity is analyzed by means of 'simulative loads' method,and a formula for calculating the sensitivity of reliability constraints on dynamic stress and displacement response is developed. Numerical example illustrated the correctness and practicability of the method proposed in this paper.
