@civilsense8: Roof trusses, part 1.Ever wondered why the Pratt truss dominates modern steel roof design over the Howe truss? It all comes down to how gravity forces the internal web members to behave. In this episode of Civil Sense, we break down the exact mechanical differences between the two classic layouts, how the diagonals handle tension versus compression, and why avoiding the buckling of long steel members dictates the way we build.On your heavy steel pitched roof projects, do you stick strictly to the Pratt layout, or do you still find a use for Howe web patterns? Let’s debate in the comments! 👇#StructuralEngineering #CivilEngineering #TrussDesign #RoofDesign #EngineeringStudents
