“…For a beam with single open crack in pinned -pinned-pinned beam, Equation (19) can be written in the following form: where By setting A ppp ¼ 0, some of the natural frequencies corresponding to specific crack location and crack depth ratio for pinned-pinned -pinned type of beam are presented ( Table 3). The first mode shape for cracked (b ¼ 0.15 and a/h ¼ 0.5) and uncracked pinned -pinned -pinned beam and the difference in the amplitude of the modes are shown in Figure 10(a),(b) respectively.…”

This article presents the study on identification of a single open crack in a straight multi-span beam using natural frequency-based non-destructive technique. The crack is assumed to be transverse and one-dimensional partial cut of a beam, and is modelled as equivalent elastic rotational spring. The effects of crack location and depth on the natural frequency for multi-span uniform beam are demonstrated. The reduction in natural frequency due to presence of crack is utilised to detect crack location and its severity. The formulation is validated experimentally.
