The 103m high mass concrete Koyna Dam is one of the largest dams in western Maharashtra, India. Located in Koyna Nagar, the dam supplies water as well as cheap hydroelectric power to neighbouring areas. It was constructed in 1963 as one of four dams built as part of the Koyna project. It has the largest catchment area of all the dams in the region, forming the Shivajisagar Lake with a length of 50km. In 1967 the dam was subjected to a magnitude 6.5 earthquake. Accelerometers on the site recorded the time histories of the event and a later survey showed that cracking had occurred in parts of the dam.
Due to the availability of field data the Koyna Dam has been the subject of a number of studies since the seismic event. One, of many studies carried out by the University of Wales in Cardiff, UK, on the dam used LUSAS Civil & Structural to investigate the dam's response to changes in numerical concrete cracking models.
