Seismic behavior of steel electric cables ladder frames in nuclear power station

At present,mostly cables bridge frames are made by thin steel plate in our country.Electric cable bridge frames in nuclear power station must have fine seismic behavior that is an important condition for safe operation or safe shutting of nuclear power station during the earthquake.This mechanical behavior and seismic characters of the steel cable ladder frames under three-dimension earthquake load and other loads are analyzed by finite element software ANSYS.And the results provide scientific basis for the design of the cable bridge frames of the nuclear power plant.
