Experimental Modal Analysis and Structural Health Monitoring of the Double Curvature Deriner Arch Dam

Arch dams have delicate sections thanks to their curvature. The fact that these are large, costly and construction takes many years increases the importance of structure. Mistakes / or accidents may occur during such structures major loss life property. Considering volumes, masses slenderness arch dams, they can be significantly affected by dynamic forces as changing water pressure, temperature, wind earthquakes. level effects what extent affect dam determined analysis made finite element model created computer. Since Finite Element Analysis is based on certain assumptions, results obtained should compared verified with experimental methods. One most suitable methods preferred in engineering modal method. Within scope study, vibration tests were carried out order evaluate determine structural behavior double curvature Deriner Dam, which has a body height 249m crest length 720m. Experimental measurements accelerometers placed appropriate places obtain mode shapes dam. characteristics using OMA software. first seven natural frequencies range 1.60-4.10Hz. As result negotiations DSI 26th Regional Directorate, acceleration data from existing accelerometer system was instantly taken continuous monitoring process initiated. This transferred web-based site condition platform created.
