WebWhat is the difference between a Pratt truss and a Howe truss? The main differences are that the Pratt truss has no force on the ends and the compression members are vertical. The Howe truss has no force on the center and the tension members are vertical instead. – The Howe truss has no net force in the center, where the load will be placed.
