The　performance　of　a　variable　curvature　friction　pendulum　bearing　(VCFPB)　is　superior　to　a　traditional　friction　pendulum　because　the　VCFPB　can　isolate　short-　and　long-　period　ground　motion　at　the　same　time.　However,　the　contact　area　between　the　spherical　polytetrafluoroethylene　(PTFE)　plate　and　the　metal　slide　decreases　with　the　increase　of　slip　displacement.　This　limits　the　isolation　performance　of　VCFPB.　In　order　to　overcome　this　drawback,　a　new　type　of　VCFPB　is　developed,　in　which　the　metal　slide　plate　used　for　a　traditional　friction　pendulum　is　replaced　by　two　orthogonal　opposed　concave　beams,　and　the　plane　PTFE　plate　is　designed　to　replace　the　spherical　PTFE.　The　mechanical　properties　of　the　new　VCFPB　were　verified　through　a　dynamic　testing,　and　the　mechanical　model　of　the　new　VCFPB　is　established　by　the　experimental　data.　©　2018,　Engineering　Mechanics　Press.　All　right　reserved.
