  Tube truss is a lattice structure composed of round rods connected with each other at the end. Compared with the traditional steel joist with open section (H-beam and I-beam), the material of the cross-section of tube joist structure is more uniformly distributed around the center and axis, so that the cross-section has good compressive and bending and torsion bearing capacity as well as large stiffness at the same time. This kind of steel structure doesn't need node plate, simple structure, easy to make and install, good structural stability and large roof rigidity. Space triangular steel tube truss shows the force mechanism of shear resistance of web bar and bending resistance of chord bar when it is subjected to vertical uniform load. The main influencing factor of axial force of chord bar is the height of section, while the main influencing factor of axial force of vertical diagonal web bar is the inclination angle between vertical web bar and vertical straight line.
