RELATION OF EARTHQUAKE INTENSITY TO GROUND MOTIONS FOR SEISMIC DESIGN
|
�´˜^�i‰p�j�F
Correlations between earthquake intensity and peak ground motions have been expressed by curves that do not adequately represent the great dispersion in the data. It is proposed to separate the data into near field and far field, then to enter the plots at levels that are consistent with the safety requirements of a project. Appropriate parameters can then be generated for velocity, acceleration, and displacement. These parameters may then form the basis for developing time histories that are suitable for dynamic analyses .
