Abstract
In order to secure the stability against strong earthquakes, isolation devices on the existing nuclear power plant have been introduced. By applying the isolation device on structures, it is possible to isolate structures from the ground motion. Therefore, the natural frequencies of the structures become longer, and the responses of the structures due to the ground motion decrease. Especially, when designing the nuclear power plant, it is important to ensure the safety of internal devices as well as the nuclear power plant itself. The floor response spectrum is commonly used in designing the internal devices. In this research, floor response spectrum is evaluated and the effect of second hardening behavior is investigated by performing earthquake analysis.
