5 General design rules
5.1 Performance of anti-seismic devices
5.1.1 General
The seismic analysis and design of structures equipped with anti-seismic devices shall be performed in
agreement with the EN 1998 series.
Design situations and rules for the definition of actions to be used for the design of anti-seismic devices
and their connections to structural members are given in the EN 1991 series and the EN 1998 series.
Design situations, design service life, durability and sustainability aspects shall be considered in
accordance with the EN 1990 series and the EN 1998 series.
The anti-seismic devices and their connections to structural members shall be designed and
manufactured in such a way that the following requirements are met, each with an adequate degree of
reliability and in accordance with the performance-based design approach as in the following:
— No failure: the anti-seismic devices and their connections to structural members shall be designed
and manufactured to withstand a seismic action having a lower probability of occurrence as defined
by the EN 1998 series, without significant local or global failure, thus retaining a residual mechanical
resistance, including – when applicable – a residual load bearing capacity, after the seismic event.
— Damage limitation: the anti-seismic devices and their connections to structural members shall be
designed and manufactured to withstand a seismic action having a larger probability of occurrence,
as defined by the EN 1998 series, without the occurrence of damage and the associated limitations
of use, the costs of which would be disproportionately high in comparison with the costs of the
structure itself.
NOTE No-failure requirement concerns the structure as a whole and, when appropriate, the anti-seismic device
and its connection to structural members. It does not concern Fuse Restraints; this device is expected to break-away
in this event which can necessitate repair or replacement.
Requirements for non-seismic design situations not covered by this European Standard, as in the case of
wind, movements due to change of temperature of the structure and settlements, are defined in
accordance with the EN 1991 series.
5.1.2 Increased reliability of structural system
According to the EN 1998 series increased reliability shall be required for the anti-seismic devices and
their connections to structural members.
In the EN 1998 series, this is implemented by applying the magnification factor γ on the seismic design
x
displacement of the anti-seismic device. Recommended values of γ for anti-seismic devices are given in
x
relevant clauses of the EN 1998 series.
NOTE Mandatory values can be given in the corresponding National Annexes if applicable.
5.1.3 Functional requirements
Anti-seismic devices and their connections to structural members shall be designed and manufactured to
function according to the design requirements and tolerances throughout their design service life, given
the mechanical, physical, chemical, biological, nuclear and environmental conditions expected.
Anti-seismic devices and their connections to structural members shall be designed, manufactured and
installed in such a way that their routine inspection and replacement are possible during the service life
of the structure equipped with anti-seismic devices.
5.1.4 Structural and mechanical requirements
Anti-seismic devices and their connections to structural members shall be designed and manufactured in
such a way that their performance characteristics conform to the design requirements, as given below:
a) Ultimate Limit State (ULS):
The verification of the anti-seismic devices at the Significant Damage (SD) and Near Collapse (NC) limit
states as ULS is associated with the seismic design situation, with due consideration of the reliability of
the structural system as defined in the relevant clauses in the EN 1998 series.
The anti-seismic devices and their connections to structural members shall be verified with an adequate
degree of reliability, ensuring sufficient strength and ductility to withstand the effects of actions in the
design situation considered. This verificat
