| Space truss has developed rapidly in China and designer for its advantage has accepted the sphere soace grid.Joints have play very important role in structure .Generally,the weided hollow ball joints are adopted .But sometime they can not satisfy the requisition of structure.So a lot of people are busy searching for joints and fouding out all kinds of joints .A new joint -welded hollow truncated joint will be now in this paper.In order to get load-carrying capacity of a truncated joint,we use ANSYS finite element method to calculate the joints with diffent kinds and find out factors influencing the result.Then the calculation formulas of load-bearing capcacity of joint under three kinds forces can be presented in ths paper .Finally,we will see the different between truncated joint and ball joint. |
