As　an　effectively　simplified　method　in　the　field　of　structural　response　analysis,　endurance　time　analysis　(ETA)　method　limits　its　application　to　pulse-like　ground　motions　because　the　endurance　time　acceleration　function　synthesized　based　on　the　frequency-domain　ground　motion　spectra　do　not　accurately　reflect　the　pulse　characteristics　in　the　domain.　In　order　to　apply　the　ETA　method　to　the　dynamic　response　analysis　of　cable-stayed　bridge　under　near-fault　pulse-like　ground　motion,　the　contributions　of　these　components　toward　the　dynamic　responses　under　different　intensity　measures　were　investigated　based　on　incremental　dynamic　analysis　(IDA),　and　the　response　prediction　model　for　cable-stayed　bridge　considering　the　effects　of　pulse　and　strength　characteristics　was　established.　Coupled　with　the　response　results　under　residual　motion　obtained　via　the　ETA　method,　the　estimated　response　under　pulse-like　motion　was　predicted　using　the　proposed　prediction　method.　The　results　show　that　the　established　prediction　model　can　accurately　express　the　quantitative　relationship　between　the　response　under　high-frequency　component　and　the　original　ground　motion.　Based　on　a　comparison　of　the　average　results　of　the　IDA　and　the　ETA　analytical　model　under　pulse-like　motion　at　0.　6g,　the　maximum　average　error　is　found　to　be　approximately　10%,　with　good　prediction　accuracy.　The　results　of　the　study　provide　technical　support　for　the　efficient　and　reasonable　calculation　of　the　dynamic　response　of　cable-stayed　bridge　under　near-fault　pulse-like　ground　motion.　©　2025　Chinese　Vibration　Engineering　Society.　All　rights　reserved.
