摘要 把单元刚度修正系数作为待识别参数 ,综合考虑了各结构参数对结构的影响 ,并运用条件优化方法对单元刚度修正系数进行计算 。 The updating coefficient stiffness is used for identification of damage. The impact of various parameter on structural stiffness is considered at the same time. Using optimal methods, the updating coefficient of element stiffness is identified. The sensitivity and effectiveness are verified by example.
