| 摘 要： | 采用动力学方法进行结构损伤诊断和参数识别时，结构的边界条件对其动力性能有较大的影响，为模拟实验条件，提出了合理的假定，并在此基础上，分析采用牛顿法和遗传算法对混凝土梁板类构件的边界参数进行了识别，正确地描述了边界条件，最后比较了两种方法各自的优缺点。

| Abstract: | The dynamic behavior of a structure is greatly influenced by its boundary conditions ,if dynamic method is applied to structural damage identification and parametcr identification. A reasonable assumption is put forward to simulate experimental con ditions. Based on the assumption,newton algorithm and genetic algorithms are separate ly used to identify the boundary parameters of the concrete beams and slabs,leading to satisfactory results. Finally comparison between the two methods is made. |
