A TENSORIAL UNDERSTANDING OF THE VARYING AXIAL FORCE OF COLUMNS SUPERPOSED UNDER THE ACTION OF 3-D GROUND SHAKINGS

抄録（英）：
The nature of multiple superposition observed in the varying axial force of columns is studied for purposes of obtaining clearer insights into the earthquake-resistant ductility design of buildings. Of its three components associated with a 3-0 action of ground shaking, two horizontal components result generally in a serious combination. while additional contribution of the remaining vertical component can become also notable for increasingly highrise buildings. Two dimensionless parameters called CQC factors are advantageously used on the horizontal plane and along the vertical axis for describing the overlapping degree of peak amplitudes during summation of three time histories. Around elastic stage of structural response, the superposition tends to be rather singular and exhibits an individually characteristic directivity. Replacement of peak amplitudes by corresponding RS values, thus leading to a tensorial formulation. is then shown to allow to understand important features in the regularities involved.
