| Abstract: | The spectral matrix of the six components of the seismic ground motions is given based onthe principal axis concept of ground motions. The matrix can be used to study the correlationsbetween the components of the ground motions and as the inputs of ground motions of randomresponse analysis for structures to multiple earihquake motions. |
