Abstract
This paper presents a finite element analysis method for damage estimation of Tsunami evacuation building. To estimate the wave force applied to the building in wave propagation problems, we have developed a three-dimensional free surface flow analysis code based on the volume of fluid (VOF) method. A numerical code based on the ASI-Gauss technique is applied to evaluate the behavior of framed structures. As numerical examples, estimation of Tsunami wave force on the evacuation buildings are presented to show the validity of the method. The applied wave force and damages of the structure obtained by the present method are compared between several inflow conditions and building shapes.
