Seismic Analysis

Services have been provided for eDf Energy at Heysham 1 and 2,  and Hartlepool Power Stations . We have completed a number of high QA Grade projects involving Seismic Qualification of new and existing structures involving complex 3D dynamic modelling using Finite Element Analysis (FEA).

Seismic Analysis is undertaken in accordance with ASCE: 4-98; Seismic Analysis of Safety Related Nuclear Structures
Where required structures are designed for Seismic Loading Conditions encountered during a 1 x 10¯⁴  event (earthquake)
Analysis is done via the SRSS Combination method using Response Spectra Graphs.


  • Seismic Analysis using the SRSS method for given response spectra graphs is undertaken using STAAD Pro finite element software
  • Existing structures are checked in accordance with appropriate design codes and with due consideration to the age of the structure. This may include where necessary retrospective assessment to historical or obsolete codes of practice
  • Finite element analysis is also used when designing/checking plate elements and reinforced concrete structures
