Response Modeling of Scoured Bridges under Near-Fault Ground Motions
This paper identifies near-fault pulse and non-pulse like ground motions based on the relative energy of velocity pulse and the peak velocity of pulse. An ANOVA analysis is performed to distinguish between main characteristics of pulse and non-pulse like ground motions, suggesting that the PGV-to-PGA ratio, energy, and peak displacement of pulse like ground motions are greater than that of non-pulse like ground motions. This paper also investigates the response of a three-span continuous reinforced concrete bridgesupported by pile foundationsunder near-fault pulse andnon-pulse likeground motions. Numerical resultsindicate that near-fault pulselikeground motions generate stronger responsethan do near-fault non-pulse like ground motions.In addition, this paper finds that scour depth have great influence onthe response of the structure. Finally, based on statistical analysis, this paper proposes anefficientparameter which performs better in reflecting the structural response to near faultpulse like ground motions.
