A rectangular tank of 10 m. width and 10 m. liquid height was tested for small ground excitation. The excitation has 0.16 second period and given by
Two finite element meshes are used: one consists of liquid elements while the other consists of elements. Figure (4.5) shows a comparison of the liquid response to the ground excitation with the analytical solution using the linear wave theory presented in . Figure (4.6) shows the effect of the mesh density on the linear liquid response.
