Abstract

This paper discusses the displacements and strains of ground caused by the crustal movements due to the 2011 Great East Japan Earthquake and the 2008 Iwate-Miyagi Inland Earthquake to investigate the damage distribution of civil engineering structures. The distributions of the co-seismic strains agree well with the ones of damaged sites of civil engineering systems. It is concluded that co-seismic strains induced by crustal movements can damage civil engineering systems when they exceed some 10^-4.7(0.00002)～10^-4.5(0.00003).
