The　static　performance　of　a　slidable　bolt-assembly　connection　between　a　double-angle　truss　and　square　hollow　structural　section　(SHSS)　column　was　studied　using　experiments　and　finite-element　simulations.　Four　specimens　with　different　sizes　or　types　of　bolt　holes　on　the　gusset　plate　were　tested　and　analyzed.　The　slip　resistance,　yield　strength,　ultimate　strength,　and　failure　mechanism　of　each　connection　were　obtained.　The　static　and　seismic　performances　of　the　connections　were　compared　with　those　of　a　welded　connection,　bolted-welded　connection,　and　all-bolted　fixed　connection.　The　results　showed　that　the　ductility　of　the　slidable　bolt-assembly　connection　exceeded　a　value　of　10,　which　was　higher　than　the　values　for　the　other　connections,　but　the　slip　resistance　was　the　lowest.　The　slip　resistance　of　the　bolt-assembly　connection　under　a　static　load　was　larger　than　that　under　a　seismic　load.　The　ultimate　strength　of　the　bolt-assembly　connection　was　equal　to　that　of　the　welded　connection,　and　the　stiffness　was　almost　the　same　as　that　of　the　welded　connection　before　the　slip.　The　ultimate　strengths　of　the　slidable　bolt-assembly　connections　were　almost　the　same　under　static　and　cyclic　loads.　The　slip　distance　increased　by　23　mm　when　the　bolt　hole　diameter　was　increased　by　2　mm.　However,　the　dimensions　and　shapes　of　the　bolt　holes　on　the　gusset　plate　only　had　slight　effects　on　the　slip　resistance,　yield　strength,　and　ultimate　strength　of　the　joint.　A　load-bearing　model　and　formulas　for　calculating　the　various　strengths　of　the　slidable　bolt-assembly　connection　were　proposed.　©　2020　Elsevier　Ltd
