Before the design of latticed portal frame can be called structurally sound, each member must be checked for the following factors: effects of axial and shear forces, possible instabilities (local, lateral, and/or column buckling), brittle fracture and deflection at service loads. Trusses are more affordable and easier to install. They are built out of hot-rolled angle sections laced together in such a way that reduces material consumption yet provides optimum support. Which consist of the side rails to support the external wall and roof purlins. These frame members are connected by rigid connections, which provide resistance against rotation. Portal frames are generally low-rise structures, comprising columns and horizontal or pitched rafters, connected by moment-resisting connections.Resistance to lateral and vertical actions is provided by the rigidity of the connections and the bending stiffness of the members, which is increased by a suitable haunch or deepening of the rafter sections.
