Seismic Analysis

Seismic Analysis and Design.
First-hand experience of earthquakes

Over the years we have gained a wealth of earthquake engineering field experience of what features make components vulnerable so we perform analytical vibration assessments knowing what needs special attention.

An experienced eye alone may be the difference between success and failure. Subsequent thorough analysis provides the formal justification to enable us to provide an unrivalled structural design service.

Some say that seismic resistant design adds 10% to the capital cost. However, it need not cost that much. Seismic design consultancy services do not need to be expensive.

First-hand experience of earthquakes

Over the years we have gained a wealth of earthquake engineering field experience of what features make components vulnerable so we perform analytical vibration assessments knowing what needs special attention.

Our first pass will be with an experienced Mark 1 eyeball and that alone may make the difference between success and failure. Subsequent thorough analysis provides the formal justification to enable us to provide an unrivalled structural design service.

Seismic Analysis

We are highly experienced in:

  • Seismic coefficient, response spectrum or time-marched computer analysis

  • Soil-structure interaction analysis

  • Structural calculations

  • Non-linear numerical modelling

  • Design and modification of plant for seismic resistance

  • Investigation into the effects of structural vibration in industrial buildings

  • Integrity assessment of bridges by natural frequency and velocity measurements

  • Substantiation of individual components

  • Seismic monitoring assessment

  • Small scale model tests

  • Assessment to design code

  • Inspection of earthquake damaged plant

  • General vibration assessment and stress analysis

  • SafePlantTM assessment to monitor the health of plants in operation.

About earthquake engineering

To DC White an earthquake is another form of vibration excitation. Any vibration, man-made or natural, can have catastrophic consequences. Whether your component or structure is a building or an electrical instrument, seismic ruggedness and qualification can be clearly demonstrated by physical test or by analysis.

Analysis is often the better and the more cost-effective route, ensuring that design improvements are made before fabrication – not after a failed vibration test.

Seismic monitoring

Seismic analysis – why is it important?

Relatively little of human civilization is designed to be earthquake resistant. Even in the developed world, earthquake resistant buildings are often seen as having intangible risks, expensive preventative measures, and as being unnecessary away from seismic hot-spots. However, a seismic analysis assessment is often highly rational no matter the location, and we can often demonstrate seismic resistance with minimal or no redesign.

Seismic monitoring

When would seismic analysis be required?

  • location: is your project based near the Asian / American / Pacific ‘ring of fire’, or the Middle East? Even in the UK it can be essential to analyse

  • it is often mandatory: is Eurocode 8 lurking within the spec?

  • is it nuclear, civil, or otherwise high value or high risk severity?

  • too big to test: vibration characteristics can often only be assessed analytically

  • reassurance: justify expenditure, improve safety credentials.

Seismic engineering projects figure extensively in our workload and we have established a reputation for innovative approaches to these problems.

Seismic assessment in research facility

We were asked by our client to perform a seismic assessment of a door for a biological laboratory in New Zealand. The primary purpose of the door was to act as an airtight seal between the 'clean-room' environment and the rest of the research facility. Because of the likelihood of earthquakes in such a seismically active part of the world, it was imperative to ensure the operational [...]
