Shaking Table Tests on a Single-Column-Bent Double-Deck Viaduct-Ⅰ Pier Model:Structural Dynamic Properties

Shaking table tests were done on a single-column-bent double-deck viaduct pier model with horizontal structural dynamic properties acquired and analyzed,which indicated that: the structure has similar mode shapes and identical mode sequence between corresponding vibration modes in longitudinal and transverse directions;the basic vibration mode alone is insufficient to account for the main horizontal structural dynamic properties;the higher-order modal frequencies are sensitive to the change of lumped mass change at the single column's upper part;cracking of the single column markedly lowers down horizontal structural modal frequencies and increases modal damping,but little influences mode shapes and mode sequences;in the cases of relatively low-intensity stimulation and small-amplitude vibration,modal tests could hardly reflect the structural damage condition after serious seismic attack.
