Abstract

Several case histories of lightweight structures performance during liquefaction from recent earthquake are reviewed. The review is focused on performance of lightweight structures in terms of liquefaction-induced vertical settlement, tilting, lateral displacement and their effects on occupancy and functionality of the structures. These case histories were reported during the 1997 Mw 7.4 Caucete- Argentina, 2007 Mw 8.0 Pisco-Peru, 2010 Mw 8.8 Chile, 2010 Mw 7.2 El Mayor-Cucapah, 2010-2011 New Zealand, and 2011 Mw 9.0 Great East Japan earthquakes. The review is performed to identify similarities, discuss conditions, and their effects on foundation and structures. Financial and economic considerations are discussed and compared for housing, i.e., cost of housing versus cost of strengthened foundation and/or improved ground. Some recommendations for residential areas are proposed.

Performance of Lightweight Structures During Liquefaction From Recent Earthquakes

Chicago, Illinois

Several case histories of lightweight structures performance during liquefaction from recent earthquake are reviewed. The review is focused on performance of lightweight structures in terms of liquefaction-induced vertical settlement, tilting, lateral displacement and their effects on occupancy and functionality of the structures. These case histories were reported during the 1997 Mw 7.4 Caucete- Argentina, 2007 Mw 8.0 Pisco-Peru, 2010 Mw 8.8 Chile, 2010 Mw 7.2 El Mayor-Cucapah, 2010-2011 New Zealand, and 2011 Mw 9.0 Great East Japan earthquakes. The review is performed to identify similarities, discuss conditions, and their effects on foundation and structures. Financial and economic considerations are discussed and compared for housing, i.e., cost of housing versus cost of strengthened foundation and/or improved ground. Some recommendations for residential areas are proposed.
