| 摘 要： | 本文提出一种识别结构系统支承刚度的新方法，该方法以传递矩阵法为基础，利用ＲＥＤＵＣＥ计算机代数语言推导以刚度参数为未知数的非线性方程组，进而解此方程组识别结构系统的支承刚度。模态试验及计算实例验证了该方法的有效性和正确性。

| Abstract: | By use of the method of transfer matrix and also the computer algebraic language REDUCE to deduce the nonlinear equation sets, the author proposes a new method to identify the stiffness of supports of a structural system.The effectiveness and the applicability of this method have been proved both by the numerical example and the test results. |
