Performance Based Seismic Design of the Main Power Building in Conventional Island of Nuclear Power Plant
-
Abstract
The main building of nuclear power station is a special kind of industrial structure, with irregular in mass and stiffness. The analysis and design should be carried on very carefully. If functional disruption or damage to the equipment during an earthquake, huge damage will be generated. the perform-based seismic design method is used to the main plant structure, the seismic bearing capacity and deformability capacity are both scrutinized, to ensure the seismic capacity of the main plant to achieve predetermined seismic aims. Design can be based on the current code for seismic design of buildings, and the evaluation of deformability capacity can be based on the element level. On this basis, five seismic waves recorded are used on the main plant structure.Results show that through reasonable design the main power building can have larger redundancy to avoid collapse under earthquake and sudden loss of bearing capacity of its key component, and can ensure the safety of the nuclear island.
