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


Is the largest UK earthquake measured at Doggers Bank in 1931

2021 - New Year, New Office

Here at Thomas Consulting we are on the move….

Exciting times after nearly 20 years in the current office at Friar Street the team are moving to a brighter, bigger accessible office at 21 China Street, Lancaster.  

The building has been part of a development undertaken by JMP Architects at their existing site.

The new office space has access directly off of China Street giving on-site parking for the Team and visiting clients; a rarity in Lancaster city centre.

As soon as COVID-19 Security and Government restrictions permit, we are looking forward to inviting all our associates and clients to enjoy a little cheese and Wine event at our new home.

We will be raising a toast to a healthy, safe and prosperous year for all.
