DID THE LARGE COSEISMIC DISPLACEMENT CAUSE THE GLOBAL OVERTURNING COLLAPSE OF THE ALTO RIO BUILDING DURING THE 27 FEBRUARY 2010 OFFSHORE MAULE, CHILE EARTHQUAKE?

摘要

A very large coseismic displacement (about 304 cm) was recorded at the city of Concepción during the moment nmagnitude (Mw) 8.8 Offshore Maule, Chile earthquake of 27 February 2010. The Alto Rio building, a 15-storey nreinforced concrete structure with two underground levels, experienced a global overturning collapse, resulting nin the death of eight of its occupants. Ever since, a lingering question has preoccupied the minds of structural nengineers and earth scientists: Did the large coseismic displacement cause the overturning collapse of this build-ning? The answer based on the analyses provided in this paper is no. Copyright © 2010 John Wiley & Sons, Ltd.
