How can I choose the best truss design?

TRUSS is an engineering design that dates back to thousands of years. Planor Truss Design is a simple triangle or attached triangles, while the cosmic rule has members that extend in a different direction to create a third dimension. Fields are used for framing bridges, roofs, floors, floors and many other structures. The best design of the truss nose usually depends on the application.

For bridges and framed roofs, a flat truss design is used. For the roof, the triangles connect the roof rafters and ceiling beams; The load spread between rafters and beams. For the bridge structure, the upper and lower part of the beam are parallel and are called chords. Solid beams to support the load on the bridge would significantly add weight and cost; TRUSS promotes loads at different degrees, depending on how far chords are located.D The King Post Truss - with one vertical member and two angle members who connect to the upper part of the vertical. Queen Post TROUSSES have two vertical membersY and the highest chord containing a box that is supported by one angular member on each vertical. Time trusses, commonly observed on the bridges, have a upper chord of a truss beam running in a fine arc, thus giving each of the lattice structure the shape of the lens.

For the cosmic truss beam is the most common design of the laundry tetramidal or pyramidal shape. The more complex space trusses combine and configure tetraedrons in different ways to distribute load, torsion, compression and tensile forces. Space Truss Designs can be observed in structures such as high voltage lines. Commercial structures of commercial building structures are also used also for commercial structures of commercial buildings.

Analysis of lattice trustees is a complex process, but the analysis is usually performed on joints or panties, more structures rather than the entire length of the members. For example, the load that is developed by a passing car or train is considered to be a moment when the tension is mainly on the joints and the voltage developed along the lengths of the members is negligible. Graphic diagrams such as Cremona or Culmann diagram diagrams are used to calculate the voltage on the rugs themselves. For further exploration of these types of loads, formulas such as the Ritter analytical method can be used.
