Example 2: Nonlinear Response to Sinusoidal Ground Excitation

The same rectangular tank used in the previous test is subjected to strong ground excitations. The excitation has 0.16 second period and given by

$\displaystyle \dot{G}_x$

$\displaystyle 1.0 \sin t\;\; \mbox{m/sec}$

A finite element mesh that consists of $10\times10$ liquid elements is used. Figures (4.7) and (4.8) shows a comparison of the liquid response to the strong ground motion with that obtained from Ref. [32]. Figure (4.9) shows the liquid mesh during the time history analysis.
