Abstract

The seismic design provisions in the NBCC 2005 are based on an earthquake hazard level higher than that used for the NBCC 1995 provisions, which involves an increase in the seismic design accelerations. This paper presents the main results of a study of the impact of the increase in accelerations on the seismic design of rigid non-structural components such as transformer tanks, reservoirs, emergency power generators, etc., and their foundations or restraints. The provisions of the 1995 and 2005 editions of NBCC for equipment located above grade level and for the calculation of base shear forces of low-rise buildings or control units for essential equipment having different lateral load resisting systems of limited ductility are presented as well. In order to get a global conclusion about the behaviour of rigid components, the analysis has been made in relation with different earthquake records.
