Seismic damage assessment of potable water systems is a very important task in proposing disaster mitigation plans. In the literature, ground motion intensities such as peak ground acceleration, peak ground velocity, permanent ground deformation, etc. have been used in the regression formulas. Nevertheless, a combined effect of these parameters was rarely studies. With reference to large GIS databases compiled after 1999 Chi-Chiearthquake, this paper adopts the approach of regression analyses to obtain empirical repair rate formulae for buried water pipelines considering the effects of ground shaking and permanent ground deformation simultaneously. The widespread observations of strong motion and ground deformation make the attained formulae very unique when compared with the data from other earthquakes. |
