Title: Comments regarding failure types in concrete walls of buildings in the February 27, 2010 Chile Earthquake.
Author(s): Ángel San Bartolomé; Daniel Quiun; Wilson Silva
Appears on pages(s): 36-48
Keywords: Chile earthquake, reinforced concrete walls, defective
Abstract:The Chile Earthquake of February 27, 2010 had outstanding features in relation to its magnitude, duration, acceleration, frequency content, destructive energy, etc. The earthquake produced serious structural damage to several reinforced concrete buildings of different heights, particularly those located on soft soils, which are capable of amplifying seismic accelerations significantly. Especially, some repetitive patterns in defective reinforced concrete walls were observed in many buildings. Its nature was discussed by some Peruvian specialists without reaching any agreement. This article analyses these defective walls taking in account all research performed, the ACI design code, and the Chilean and Peruvian Codes. In this way, some improvements to structural design are proposed considering the lessons left by this earthquake.
