The truss is produced by the new bright truss manufacturer, which greatly guarantees the output and quality. What kinds of trusses are stable in the truss structure? Answer: 1. Trapezoidal truss 2. Polygonal truss 3. Triangular truss Trapezoidal truss and triangular truss have improved the force of the members, and it can be more easily used in the truss to meet the technical requirements of some industrial plants. If the upper and lower chords of the trapezoidal truss are parallel to the parallel string truss , the force of the rod is slightly worse than the trapezoid, but the type of the web is greatly reduced, and it is mostly used in bridges and trestles. Polygonal trusses are also called polygonal trusses. The upper chord is located on the quadratic parabola. The chord is arched to reduce the bending moment generated by the inter-segment load, but the manufacturing is more complicated. Under the uniform load, the shape of the truss is similar to that of the simply supported beam. Therefore, the force distribution of the upper and lower chords is uniform, the axial force of the web is small, and the material is the most economical. It is a truss form commonly used in engineering.
