Local and global effects of forward directivity

Local and global effects of forward directivity

Previous studies have revealed that near-fault ground motions perpendicular to the fault slip are very destructive for structures. Due to the common use of moment resisting frames and the importance of near-fault strong motions, the local and global effects of long-period (Tpulse>0.7s) pulse-like...
