SERIES Training Course - Bristol, Jan 11-12 2011

Typical Qualification ProcessPreliminary meetings to agree test specification including

Equipment requirementsMain test spectraNumber and amplitude of shakes Exploratory test requirementsDetails of functions testing

Preparation of test documentation – QP, TMSGenerate shakes ready for testingArrival of specimen, examination for transport damageMount specimen on shaking tableInstall instrumentationFunctional testsExploratory testsFunctional testsMain seismic tests including basic data processingFunctional testsRemove specimen from shaking table and return to clientFinal data processing and produce test report



Project Documentation• Test Method Statement• Quality Plan

• Equipment Details and Calibration Procedures• Test Instrumentation Record

• Earthquake Simulator Test Log Sheets• Exploratory Test Data• Test Response Spectra• Other Instrumentation Data (displacements)• Digital Photographs• Digital Video Records• Record of Test Witnesses

• Functional Monitoring and sign off sheets



Calibration Certificates• Calibration of standalone instruments • Chain calibration of accelerometers



Calibration tolerances• ± Errors from calibration laboratory and from differences

in instrument gains

• Accelerometers+Fylde amplifiers+FERN EF6 system +5.38% -3.01%Power supply +/- 0.33%MSXB 028 = SIMACQ version 3.00 +/- 0.33%

Total chain uncertainty + 6.04% - 3.67%

• Therefore ratio of all achieved to required spectra values must be 1.0604



Test Instrumentation Record



Test Log Sheets



Exploratory Data

Main Natural Frequency: 9.8 Hz Damping: 2.4 %

• Checking natural frequencies of specimen• Measurement of actual damping levels• Calculations using spectrum analyser or

custom software• Results may be used to modify main test

sequence



Exploratory Tests• Sine sweep test data• In-house processing of results



Acceptable RRS Matches• Low frequency enveloping

(IEEE 344 If the specimens show no resonances below 5Hz, enveloping is not a formal requirement for frequencies below 3.5Hz)

• Over enveloping



Table Response Spectra

Fail Pass



Specimen Response Spectra

Table Test Specimen



Displacement Data• Displacement monitoring during a BELLCORE test (limits generally ± 75mm)



Functional Monitoring• Output voltage from pressure transducer recorded during seismic testing



Specimen Damage

•.

• Minor damage – to enclosures, doors etc



Remedial Actions• Bolting arrangements



Remedial Actions• Equipment dislodged during shakes



Record of witnesses
