摘要
本文主要研究裂缝对梁结构振动参数的影响。给出了一种只与裂缝位置有关,而与裂缝深度无关的量。据此,提出了一种近似估计梁结构中裂缝位置的方法。应用的实例表明,该方法是可行的。
In this paper, the effect on the vibration parameters caused by a crack in a girder construction is investigated. And this effect may be measured by tracing a quantity which only relates with the location of the crack but not the depth of the crack. By virtue of the above, a method is suggested which may be used to detect approximately the location of thecrack in a girder construction. An example is given which shows that the suggested method is feasible.
