Numerical simulation of earthquakes' impact on facilities by grid-characteristic method

The aim of this work is to study the earthquakes' impact on the ground buildings and underground facilities. The use of grid-characteristic method makes possible to take into account the physics of arising wave processes. The use of hierarchical grids allows to perform a calculation directly from the earthquake source to the ground buildings. We have investigated the arising area of cracks in this ground building (two-storied house) at different times from different types of waves. Also we considered the impact of earthquake on the underground facilities.
