Sažetak
The pounding of two adjacent 3-bay and 5-bay 5-storey frames is studied in this paper. These frames are analysed under eight different ground motions in two left-to-right and right-to-left directions for 17 separations between them. Park- Ang damage indices of adjacent frames are studied. The results show that the use of elastic impact elements is generally conservative. The direction of ground motion influences the level of damage of colliding structures. The separation equalling to 1% of storey height can eliminate or strongly decrease pounding force.
