Abstract
This paper discuses the effectiveness of scanning laser techniques for measuring the dynamic response of the Olmsted Prototype Wicket Dam at the Smithland facility, Smithland, KY. Full-scale prototype experiments at the Smithland facility were conducted to facilitate the development of an innovative wicket for the Olmsted Dam. The Olmsted Locks and Dam (LD) is the Corps largest navigation project which will replace the existing LD 52 and 53 on the lower Ohio River. The proposed wickets will be used to control the water flow and maintain a navigable pool on the lower Ohio River. The laser techniques' effectiveness to extract the modal information for large civil structures is discussed in this paper. Experimental dynamic responses of the prototype wickets are examined to evaluate the design performance and structural integrity of hydraulically actuated wickets for the proposed Olmsted LD. Experimental modal results were used to update the analytical and physical scaled models.
