Abstract：Inordertodevelopthegridstructureof theownerlesspurlinboltballjint，anewshearboltballjoint wasdesiged， andtheballjointsof three newbolts with diferentbolt diametersof M24，M27and M3Owere testedthroughthecompreson， tensionand shear tests，andtheircomponentsandoverallmechanical properties were studied.Theresultsshowthat when the jointiscompressed，thenew node sleeveis morecompressivethan theordinary joint，andthenew nodebolt bears acertain force.When tensioned，themechanicalvariationlawofeachcomponentof thetwo joints isconsistent.Whensubjected to bendingshear，theshearresistanceof thenewjointis improvedtoacertain extent，theultimatebending momentsof thenew M24，M27 and M30 joints are increased by 2 % ， 6 % and 13 % respectively. The test results are compared with the simulation results，and the maximum error is not more than about 10 % ：
