The　present　study　develops　a　novel　type　of　active　joint　node-bolt　fasten　wedge　(BFW)　active　joints,　aiming　to　investigate　the　load-bearing　capacity　of　a　BFW　joint　in　a　quantitative　way　and　put　forward　precise　formulas　for　its　yield　load　and　compression　rigidity.　To　achieve　this,　indoor　axial　loading　tests　were　conducted　on　two　BFW　joints,　accompanied　by　a　set　of　numerical　simulations　with　the　finite　element　approach　implemented　in　ABAQUS.　Parametric　research　was　then　conducted　to　assess　the　impact　of　various　factors　on　the　yield　load　and　initial　compression　rigidity　of　BFW　joints,　leading　to　the　derivation　of　precise　calculation　formulas　for　accurate　prediction　of　these　parameters.　The　key　findings　indicate　that　enhancing　the　bolt　strength　from　10.9　to　12.9　significantly　improves　mechanical　performance.　Under　axial　compression,　the　final　bearing　force,　yield　load,　and　initial　compression　rigidity　increase　by　0.86,　1.06,　and　0.15　times,　respectively.　Numerical　models　accurately　predict　joint　behavior　under　axial　force,　confirming　their　reliability.　Parameter　studies　reveal　that　increasing　web　and　eaves　thickness,　bolt　strength,　and　diameter　improves　bearing　capacity,　while　splint　thickness　has　little　effect.　The　fitting　formulas　introduced　can　precisely　estimate　yield　load　and　rigidity,　providing　practical　value　for　engineering　applications.　©　2024　Tongji　University.
