Description
This paper points out the refinements about the seismic damage estimation formulas and various correction factors for buried water pipes through a comparative analysis between the damage to water pipelines in Sendai City and Iwaki City caused by the 2011 off the Pacific coast of Tohoku Earthquake and the damage estimated by four kinds of existing damage estimation formulas.<br> In addition, this paper shows that an existing damage estimation formula using modified correction factors, such as pipe material, pipe diameter and soil condition, enables us to improve the damage estimation accuracy.
