Local and global effects of forward directivity

Sažetak
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 ground motions are studied on 5 samples of steel moment resisting frames by considering variations in the height of models. Results obtained show the forward directivity increases global and local demands of models for about 1.1 to 2.6, and 1.2 to 3.5 times, respectively.
