Abstract
AbstractThis paper presents two physics‐based, orientation‐independent intensity measures that truly captures the three‐dimensional motion of an orthogonal array of accelerometers and are more appropriate for seismic structural design. This is achieved by processing all three components of the record simultaneously, rather than simply combining the results of processing each component in isolation. Compared to other commonly accepted orientation‐independent intensity measures, it was found that horizontal seismic demand may be systematically underestimated by as much as 29% in the worst‐case scenario. In addition, these new measures are much more computationally efficient than the current ones, as they reduce the number of response spectra calculations per seismic record to just 2 or 3, depending on the measure. Thus, the orientation‐independent intensity measures introduced here optimize the processing of seismic records and may help to reduce the uncertainty of the estimation of the seismic acceleration for structural design.
