동수압을 고려한 콘크리트 중력식 댐의 내진안전성 평가

Seismic Safety Evaluation of Concrete Gravity Dams Considering Dynamic Fluid Pressure

  • 발행 : 2006.02.28

초록

Seismic safety evaluation of concrete gravity dams is very important because failure of concrete gravity dam may incur huge loss of life and properties around the dam as well as damage to dam structure itself. Recently, there has been growing much concerns about earthquake resistance or seismic safety of existing concrete gravity darns designed before current seismic design provisions were implemented. This research develops the dynamic fluid pressure calculation using 'added mass simulation'. The actual analysis using structural analysis package was performed. According to the analysis results, the vibration which is transverse to water flow seems to be very critical depending on the shape of the dam.
