The Seismic design for nuclear facilities has been subject of complex
analysis of the type usually performed for nuclear power plants. For the
purpose of ensuring seismic safety for nuclear facilities with limited
radioactive inventory, a simplifi
ed approach was adopted by the IAEA
safety guides with emphasis on appropriate construction and detailing
principles rather than sophisticated dynamic analysis. This work presents
the equivalent static approach, with an application for a frame element, a
dynamic analysis is also achieved using a computer program (DRAIN –
2DX) with real (time – history earthquake) for the purpose of
comparison, the results lead to some observations and notes which have
to be taken into account for the seismic safety design.
The study
will examine the effect of changing the diameter of the longitudinal
and lateral reinforcement on the carrying capacity of the concrete
columns and compare the value of the compressive strength of
concrete, which is associated with the theoretical relations provided
by (Mander), (Park et all) by building an analytical model using
finite element Program ANSYS.
