Abstract EN
In the near-field earthquake, forward directivity effects cause long-period pulse with a short effective time and a large domain in the velocity time history.
This issue increases the ductility needs of structures, and in recent decades, the destructive effects of these kinds of records have been evaluated in comparison with far-field earthquakes.
This brings about the necessity to compare a structure’s behavior subjected to vertical components of near-field (NF) earthquakes, including forward directivity effects vs.
the effects of vertical components of far-field (FF) earthquakes.
The present study investigated 3-, 5-, 8-, and 20-story steel moment frames with special ductility (SMF) through which modeling effects of panel zone have been applied, subjected to vertical component of near-field (NF) earthquakes with forward directivity and the vertical component of far-field earthquakes.
By investigating the results, it can be clearly seen that the average values of the maximum displacement, shear force of the stories, and the velocity of each story under the impact of the near-field earthquake are greater than the amount of that under the effect of a far-field earthquake.
However, this comparison is not valid for the amount of acceleration, axial force, and moments in the columns of the structures accurately.
