Common stage truss structure of the folding stage

The main structure of folding stage is truss, common stage truss structure on the market basically has the following:

Polygon truss: polygon on the truss bottom chord axial force distribution even, diagonal axial force is small, the materials the most provinces, a truss form is commonly used in engineering.

Due to the triangle truss: truss chord internal force difference is bigger, material consumption is not reasonable, more used for roof.

Vierendeel truss: axial force distribution of vierendeel truss rods and polygon truss are similar, but under asymmetry load rod end bending moment value change is bigger. Advantage is that the node is the intersection of bar is less, construction convenient manufacturing.

Trapezoid truss: trapezoid truss trapezoid parallel to the upper and lower chord of the truss is parallel chord truss, bar stress distribution is trapezoidal slightly less, but greatly reduced diagonal type, more used in Bridges and piers.
