Modal Spectra Seismic Analysis for non-uniform excitation

OSTI ID:5768726
The Independent Support Motion (ISM) method of Modal Spectra Seismic Analysis (MSSA) applies to structural systems subject to non-uniform excitation. This paper presents the merits of the ISM method over the Envelope Response Spectra (ERS) method of MSSA, discusses adequacy of the supports group definition, evaluates the effect of support motions correlation, and explains the response patterns and dependency on problem characteristics.
