N2  - The main objective of Performance Based Design is determining the structural demands for earthquake loadings. For a good estimation of structural demands, the relation between ground motion parameters and structural demands must be known. Near fault ground motions are significantly different from far field ground motions. Depending on the fault mechanism, ground motions may contain distinct pulse in velocity and permanent displacement in displacement records. These are increase the near fault ground motions damage potential. Forward directivity occurs in faults normal direction and damage potential of this ground motions are high. But for all records, psychically, it is not possible to determine the fault-normal and fault-parallel directions. In literature, to overcome this complexity the maximum velocity direction has been proposed. In this study in addition to maximum velocity direction two new directions, maximum drift spectrum intensity and maximum spectral velocity, were determined which are very effective as fault-normal direction. The efficiency of maximum velocity direction depends on  ratio of pulse period to structural period. In the case of high value of this ratio, the maximum acceleration ratio is more destructive.
