Warren Truss Pros and Cons
Warren Truss Pros and Cons
There are no longitudinal members in the Warren truss; instead, only angled cross-members connect them together, resulting in spaces that are alternatively inverted Equilateral triangles along their length. With no vertical components, loads on the diagonals alternate between compression and tension. Elements in the center, on the other hand, must support both tension and compression in response to live loads. This design has a good balance of strength and weight savings because of the way the materials are used. Due to the same length of the girders, this design is perfect for prefabricated modular bridges. Known as a Warren truss, or simply an equilateral truss, this structural design makes use of equilateral triangles to save …
