Description

<p>The UAV having hammering mechanics was developed and the applicability of hammering test was verified. The characteristics of UAV is that it can conduct hammering test continuously during movement control by traveling mechanics after touching it to target. In this paper, firstly, the applicability of hammering mechanics and evaluating methodology of sound parts as first screening to detect damaged parts were verified by using experimental specimen embedded imitated crack. Then, the method was applied to actual bridges which are a sound condition bridge and deteriorated bridge. As a result, it was confirmed that the hammering mechanics in the UAV and the proposed evaluation method of sound parts can conduct hammering test for actual bridges.</p>
