Performance of tall buildings in Santiago, Chile during the 27 February 2010 offshore Maule, Chile earthquake

Abstract

There are many modern tall buildings in Santiago that were subjected to the 27 February 2010 earthquake in Chile. Although there was not widespread damage in Santiago, there was notable damage to some tall concrete buildings that may have resulted from lack of proper detailing, the absence of 135° seismic hooks and inadequate confi nement of walls in the boundary zones. These caused buckling of the main bars and tension compression failure of the walls.
