cause of damage in buried pipelines due to seismic wave propagation. The use of
8g as damage indicator in pipeline fragilities has not been very extended due to the
difficulties to get accurate estimates of it; the fragility function proposed by O'Rourke
and Deyoe (2004) is the only known case by the author. Recently, a novel parameter
for pipeline damage estimation in soft soils has been proposed in terms of PGA and
PGV: PGV2/PGA (Pineda and Ordaz, 2007).
From the six ground motion parameters that have been employed as damage
predictors in pipeline fragilities, three of them (sg, PGV, and PGV2/PGA) are
analyzed in this paper. MMI and PGA are not included in this revision since it has
been demonstrated that PGV is better damage predictor than those two parameters.
PGD is not included in this analysis since it has not extensively been used as damage
predictor in pipeline fragilities mainly due to the difficulties found in its calculation.
The double integration of acceleration time histories and other processes like
tapering, filtering, and correction of base line, could produce unreliable PGD
In the following two sections the theoretical basis for the use of PGV and PGV2/PGA
as pipeline damage predictors are presented, respectively. Since the main objective of
this paper is to discuss the future challenges for developing pipeline fragilities, it is
suggested that the interested readers look for further information on pipeline
fragilities in the references shown in Table 1.
