The　seismic　soil　response　and　soil-buried　infrastructure　interaction　are　of　immense　importance　for　the　resilience　of　urban　centres.　Shake　table　testing　offers　an　efficient　tool　for　modeling　the　seismic　soil-structure　interaction.　This　paper　presents　the　design　and　commissioning　of　a　suspended　continuum　soil　box　supported　on　an　array　of　shake　tables　to　enable　simulating　homogeneity　and　inhomogeneity　of　soil　and　non-uniform　seismic　excitation　of　extended　buried　structures　such　as　pipelines　and　tunnels.　The　large-scale　shaking　table　model　involves　a　steel　box　7.3　m　x　1.4　m　x　1.2　m　supported　by　3　shake　tables.　It　comprises　3　active　rigid　boxes　(2　end　boxes　and　one　middle　box)　supported　on　3　shaking　tables　and　2　passive　(suspended)　soft　joint　boxes　to　provide　continuous　soil　medium.　The　continuous　box　design　is　modular　and　allows　its　expansion　to　be　supported　by　the　available　9　shaking　tables　for　even　much　longer　soil　continuum　model.　The　developed　test　setup　was　used　to　investigate　the　seismic　response　of　free-field　soil　to　verify　the　performance　of　the　soil　continuum　box.　The　sand　test　model　was　instrumented　with　arrays　of　accelerometers　embedded　along　its　height　within　both　rigid　and　suspended　boxes　to　evaluate　the　effect　of　the　test　setup　on　the　ground　motion　characteristics　in　both　segments.　Dynamic　performance　of　the　continuum　box　is　examined　by　comparing　the　results　of　shaking　table　tests　on　the　box　empty　and　box　containing　a　sand　model.　The　results　demonstrat　that　the　soil　box　did　not　experience　resonance　with　the　sand　model,　hence　it　did　not　affect　its　response　to　the　shaking.　A　quantitative　analysis　is　conducted　to　evaluate　the　box　boundary　effects　on　the　soil　seismic　response　in　terms　of　the　L2-norm,　mu,　the　acceleration　time　history　waveform　and　Fourier　spectrum　characteristics　at　soil　surface　and　0.7m　below　surface.　The　consistency　of　surface　peak　acceleration　under　different　seismic　excitations　and　intensity　levels　are　compared　in　terms　of　standard　deviation,　beta.　The　results　demonstrat　that　the　developed　suspended　continuum　model　box　performed　well　and　can　simulate　the　continuity　and　boundary　conditions　of　free-field.
