Experiments　on　two　reactive　powder　concrete　(RPC)　model　arches　subjected　to　concentrated　loads　at　quarter-span　have　been　carried　out.　A　finite　element　(FE)　procedure　considering　both　material　and　geometric　nonlinearities　is　developed　and　the　numerical　predictions　agree　well　with　the　test　results.　The　load-displacement　curves,　cracks,　strains,　failure　modes　and　ultimate　load　capacities　of　the　arches　are　analyzed　and　compared　with　the　results　of　conventional　reinforced　concrete　(RC)　model　arches.　FE　analytical　and　experimental　results　show　that　the　RPC　arches　behave　similarly　to　RC　arches.　The　RPC　arches　also　fail　due　to　the　mechanism　formed　by　four　plastic　hinges　caused　by　cracks　in　tensile　areas.　The　ultimate　load　capacity　of　RPC　arches　can　be　estimated　by　the　limit　analysis　method,　similar　to　RC　arches.　It　is　concluded　that　RPC　arches　have　greater　load　capacity,　stiffness　and　anti-cracking　resistance　than　those　of　the　RC　arches　owing　to　the　superior　properties　of　RPC.　The　widest　crack　in　RPC　arches　is　only　25%~50%　that　of　RC　arches　under　the　same　load.　At　a　same　load　level,　the　cross　section　area　and　self-weight　of　the　RPC　arch　can　be　about　one　third　less　than　those　of　the　RC　arch,　indicating　that　the　application　of　RPC　would　improve　the　spanning　capability　of　arch　bridges.
