Based on the sites relative to the fault rupture, the spatial positions of the records are divided into three regions, named Forward Region (FR), Middle Region (MR) and Backward Region (BR). Three groups of near-fault ground motions in above regions are selected as the input from the 1999 Chi-Chi earthquake. The Sutong Cable-stayed Bridge (SCB), with a main span of 1088 m, is taken as an example. The results reveal that the properties of near-fault ground motions have obvious correlations with the dynamic responses of the bridge in 3 regions. The PGV and PGA can be identified as the key parameters governing the bridge response in MR. The intensity measure parameter of near-fault ground motions in FR suitable for the super-span bridge systems can be taken as PGV and PGV/PGA. For the bridges located in BR, the PGA, and fault distance can be preferentially selected as the governing parameter in BR.
