Area: Characterization of multi-component seismic excitations
Earthquake ground motion consists of six directional components: 3-Transational components along X, Y and Z Axis and 3-Rotational components about X, Y and Z (2 Rocking and 1 torsional components). Three directional components are routinely measured, and huge amount of data are available which led to significant research in characterization of translational components. However, recording of rotational components are relatively new.
The present technologies to measure rotational components are not currently included in standard strong-motion accelerometers. Although, few recordings have been reported recently, their credibility is not adequately accessed. Our research is focused on characterizing the multi-component design spectra and possible influence on structural design. We also aim to address the six-component directional combination rule.
