Evaluation of Park-Ang Damage Indicator in collisions of two adjacent frames under the near-fault field disturbances

Pounding of adjacent buildings during earthquake causes local and total damages in buildings. One of the ways to reduce the damage in pounding, is creating a separation gap between two adjacent buildings. Park-Ang's damage index computes the amount of damage to the structure, according to the a...

One of the ways to reduce the damage in pounding, is creating a separation gap between two adjacent buildings.

In this study, estimates the effect of far-field and near-field earthquakes, on the Park-Ange damage index in pounding of two adjacent frames and separation gap is equal to the value proposed by Standard 2800.The frames are arranged in three, regular and irregular soft story and very soft story frames on the first floor.
