a) The structure should not collapse nor experience other similar forms of structural failure due to severe earthquake accepted limits (serviceability limit state: SLS). during the service life of the structure with damage within ground motions which may be expected to occur at the site b) The structure should withstand moderate earthquake (ultimate limit state: ULS).
