Abstract : A general computer program based on the finite element method of analysis of linearly elastic dam cross-sections subjected to earthquakes is presented. It is applicable to the analysis of concrete gravity dams and earth dams. This program utilizes a recently developed plane stress quadrilateral element, and the equations of motion are solved by the mode superposition method using the fastest known subroutines for computation of eigenvalues and eigenvectors. The FORTRAN IV listing of the program is included and the usage and capabilities of the program are illustrated by examples. (Author)
