核电站用钢制梯架式电缆桥架抗震性能研究

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

目前,国内绝大部分电缆桥架均采用薄钢板制造。核电站中的电缆桥架必须具有良好的抗震性能,这是核电站在地震中安全运行或安全停堆的重要条件。采用有限元软件ANSYS对核电站中的钢制梯架式电缆桥架在三向地震动和其它载荷作用下的抗震性能和力学性能进行了计算分析,分析结果为核电站用电缆桥架的设计、制造标准化提供科学的依据。

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...
