摘要

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