In　order　to　study　the　aseismic　performance　of　a　lightweight　bridge　with　concrete-filled-steel　tube　(CFST)　composite　truss　girders　and　lattice　piers,　took　Ganhaizi　Bridge　as　a　prototype,　one　scale　specimen　of　1:8　with　two　spans　and　three　lattice　high　piers　was　designed　for　a　multi-shaking　table　test.　The　test　was　carried　out　on　the　earthquake　simulator　of　a　unique　triple　shaking　table　array　system　in　Fuzhou　University,　China.　Adopted　the　design　seismic　wave　of　a　real　bridge,　its　basic　dynamic　characteristics,　aseismic　performance　and　failure　characteristics　were　studied.　The　results　indicate　that　the　ratios　of　the　frequency　to　the　displacement　between　a　specimen　and　a　real　bridge　are　corresponding　to　a　similitude　relationship.　Under　a　transverse　or　a　longitudinal　excitation,　the　acceleration　in　lattice　zones　significantly　amplifies,　and　decreases　the　acceleration　on　a　concrete　deck.　The　strain　under　the　transverse　direction　is　larger　than　that　under　the　longitudinal　direction,　meanwhile,　it　is　unnecessary　to　consider　the　combination　of　two　directions.　The　displacement　on　the　top　of　a　pier　is　less　than　the　limitation　value　under　design　ground　motions.　The　specimen　is　not　failed　for　all　testing　cases,　which　reveal　that　a　lightweight　bridge　with　CFST　composite　truss　girders　and　lattice　piers　has　a　favorable　aseismic　performance.
