Direct finite element method for nonlinear analysis of semi-unbounded dam-water-foundation rock systems
Løkke, Arnkjell; Chopra, Anil K. (Journal article, 2017)A direct finite element method is presented for nonlinear earthquake analysis of interacting dam–water–foundation rock systems. The analysis procedure applies viscous damper absorbing boundaries to truncate the semi-unbounded ... -
Direct finite element method for nonlinear earthquake analysis of 3‐dimensional semi‐unbounded dam–water–foundation rock systems
Løkke, Arnkjell; Chopra, Anil K. (Journal article, 2018)A direct finite element method for nonlinear earthquake analysis of 2‐dimensional dam–water–foundation rock systems has recently been presented. The analysis procedure uses standard viscous‐damper absorbing boundaries to ... -
Earthquake Analysis of Concrete Gravity Dams: Review and Modernization of Two Analysis Procedures
Løkke, Arnkjell (Master thesis, 2013)A two-stage procedure has been proposed for the elastic analysis phase of seismic design and safety evaluation of concrete gravity dams: (1) response spectrum analysis (RSA) in which the peak value of response is estimated ...
