Eurocode 8 EN1998: Design of Structures for Earthquake Resistance
Calculations for Eurocode 8: Analysis of seismic isolation system, earthquake action during construction, mononobe-okabe dynamic earth pressure coefficient KAE
Calculation of the design response spectrum in terms of spectral acceleration representing the seismic action in the horizontal or vertical direction. Applicable for the design of ductile structures where the inelastic behavior is taken into account explicitly with the behavior factor q.
Calculation of the elastic response spectrum in terms of spectral acceleration and spectral displacement representing the seismic action in the horizontal or vertical direction. Applicable for the design of structures that remain in the elastic range, seismic isolation systems, and calculation of seismic displacements.
Preliminary analysis of seismic isolation system with the equivalent linear single-degree-of-freedom (SDOF) method. Applicable for seismic isolation system with FPS, LRB, HDRB isolators and viscous dampers.
EN 1998-1:2004 Section 10.9.2, EN 1998-2:2005+A2:2011 Section 7.5.4
Calculation of the reduced earthquake ground acceleration applicable during the construction phase of the structure as a function of the duration of the construction stage (applicable for any type of structure, not only bridges)
