Seismic problems figure extensively
in our workload and we have established
a reputation for innovative approaches to these problems achieving
cost-effective
solutions in short time-scales.
We have wide experience, covering such
diverse aspects as:
Seismic assessment of critical plant
Seismic design
Seismic monitoring
Inspection of earthquake damaged plant
Recommendations for repair to earthquake damage
We have been responsible for the seismic design of many structures
and components, ranging from pipework support brackets to the design of
an emergency cooling tower for a nuclear power station.
We have conducted various types of analyses, including
Seismic coefficient based calculation;
Response spectrum based computer analysis;
Soil-structure interaction
analysis;Time-marched, linear and non-linear numerical modellingInvestigation
into the effect of structural vibration in industrial buildings.
Machinery –
design of remedial measures for fans, fan casing, shafts and bearing
assemblies.
Process plant –
long term remote electronic monitoring of the vibration of safety
critical pressure vessels.
Human response
to vibration, for example, hand/arm vibrations – "White finger"
Fatigue – design
and analysis of wind turbine blades.Automotive – ABS
braking characteristics under swerving manoeuvres in conjunction
with the Institute of Traffic Accident Investigators. (ITAI)
Integrity
assessment of bridges by natural frequency and velocity
measurements.
Our engineers are experienced in the following testing areas:
Structural mode measurement, on or off-siteSmall scale model testsSeismic arrays
Assessment to design codes
Vibration measurementLong term monitoringComputer modellingRemedial measures |
