摘要
在分析国内外文献的基础上 ,通过 1 2缩尺的 3层砖房的模型试验验证了用反演理论建立的动态参数和砌体平均抗压强度的关系。提出了用残余力向量判别结构损伤部位的方法 ,并在实际工程中应用 ,拓宽了采用动态法检测现有砖房质量的思路。
With analytical computation of inversion theory and pulsating test technique, the relation of modal parameters and structural practical strength is verified with three\|story brick building of half scaling. It is given in this paper that residual force vectors is used to locate damaged positions. The method is used to assess construction quality successfully in practical engineering, which widens the thought on the existing multi\|story brick building′s quality inspection with dynamics method.
