Abstract

This study presents the mechanical behavior of a ventilating window (a tsunami damper) on the building wall of a nuclear power plant. The window, which is under development, is used to ventilate a machinery room and the building under normal conditions, but it also provides a safety barrier for critical equipment against a tsunami caused by an earthquake. A finite element analysis was conducted to investigate the deflection and the stress distribution of the window under given loading conditions. With symmetry, a one-quarter portion of one window was modeled, and the pressure due to a great tide is assumed to be 7 bar. A structural analysis of the assembled frame, composed of a blade and casing, was also conducted using contact conditions to find the stress and strain configurations caused by the applied pressure.
