| 摘 要： | 研究了混凝土结构中钢筋锈蚀参数的识别问题.在考虑混凝土的塑性变形和梁的拉区裂缝的基础上，利用能量法导出梁的自由振动的数学模型，从而得到梁的低阶频率；然后运用最小二乘法建立目标函数，通过非线性迭代识别出钢筋锈蚀参量.图2，表1，参6.

| Abstract: | The identification of rusting parameters for concrete reinforced bars is studied in this paper.The mathematical dynamics model of the damaged concrete beam is proposed by the means of the energy method with considering the plasticity of concrete and the cracks in the drawn region,and some low-order frequencies are obtained from here.The objective function is obtained by the least square method,then the rusting parameters about the bars are identified by the non-linear iteration.2figs.,1tab.,6refs. |
