While the Warren truss and modified Warren truss are generally … It’s characterized by its diagonal members, which are inclined with the same angles. This pattern of diagonal and vertical truss members leads to that the loads are evenly distributed across the truss. The only difference between Pratt and Howe trussis that the diagonal members of the Pratt truss are facing … See more The static system of the Pratt truss is characterizedby having 1. hinge connections at all nodes 2. a pin and roller support, which makes the system statically determinate. Therefore, the internal forces can be … See more The pros and cons are basically the same as for the Howe truss, because of their similar shape and geometry. See more Let’s say our Pratt Truss is a bridge structure. Therefore, the truss is exposed to dead and traffic load mainly on the bridge deck, which transfers the loads to the bottom chord. We also simplify and say that the design … See more Now, that you got an overview of the Pratt Truss, and how we calculate its internal forces, you can learn about loads, because every truss is exposed to loads. 1.
