Operating Deflection Shapes of a High Rise
In this example time domain
Shapes (ODS) of a 54 storey building in downtown Los Angeles, California are
The 54 storey building in LA
|The displacement deflection shapes are based on a 20 channel
earthquake record and the recorded event is the 1994 Northridge
The measurements and the input file has been provided by Professor
Carlos Ventura, University of British Columbia, Canada.
In the analysis the measured acceleration signals
were double integrated and calibrated to obtain the displacement Time Domain Operating
Deflection Shapes. All of this is automatically performed in the ODS task of ARTeMIS
