| Research Abstract |
We developed a distributed memory parallel program to simulate the failure of concrete walls under tsunami wave impacts. The program is validated by reproducing some experimentally observed crack patterns reported in literature. The validated program is used to successfully reproduce the observed crack patterns on full scale concrete wall models, tested at the Large Hydro-Geo Flume Facility (LHGF) of the Port and Airport Research Institute, using the experimentally observed pressure data as an input.
