This　study　is　devoted　to　the　experimental　validation　of　the　multi-type　sensor　placement　and　response　reconstruction　method　for　structural　health　monitoring　of　long-span　suspension　bridges.　The　method　for　multi-type　sensor　placement　and　response　reconstruction　is　briefly　described.　A　test　bed,　comprising　of　a　physical　model　and　an　updated　finite　element　(FE)　model　of　a　long-span　suspension　bridge　is　also　concisely　introduced.　The　proposed　method　is　then　applied　to　the　test　bed;　the　equation　of　motion　of　the　test　bed　subject　to　ground　motion,　the　objective　function　for　sensor　location　optimization,　the　principles　for　mode　selection　and　multi-type　response　reconstruction　are　established.　A　numerical　study　using　the　updated　FE　model　is　performed　to　select　the　sensor　types,　numbers,　and　locations.　Subsequently,　with　the　identified　sensor　locations　and　some　practical　considerations,　fiber　Bragg　grating(FBG)　sensors,　laser　displacement　transducers,　and　accelerometers　are　installed　on　the　physical　bridge　model.　Finally,　experimental　investigations　are　conducted　to　validate　the　proposed　method.　The　experimental　results　show　that　the　reconstructed　responses　using　the　measured　responses　from　the　limited　numberof　multi-type　sensors　agree　well　with　the　actual　bridge　responses.　The　proposed　method　is　validated　to　be　feasible　and　effective　for　the　monitoring　of　structural　behavior　of　long-span　suspension　bridges.　©　2016,　Science　China　Press　and　Springer-Verlag　Berlin　Heidelberg.
