Comparison of Conventional Steel Roof Trusses with Tubular Trusses …
Webof the truss. This Howe truss configuration is two identical two-dimensional trusses, connected by intervening members. This particular truss consists of four bays of the same length. The height of each bay is equal to its length. The intervening members have the same length as the length of each bay. The overall span is 2 meters. Figure 1. WebPratt trusses are commonly used in long span buildings ranging from 20 to 100 m in span. In a conventional Pratt truss, diagonal members are in tension for gravity loads. This type of truss is used where gravity loads are predominant (see below left). An alternative Pratt truss is shown (below right) where the diagonal members are in tension ... binary translation rapidtables

While the configuration appears to be the same as a Howe truss, the Pratt truss’s verticals functioned as compression members and diagonals functioned as tension members.
