Abstract In structural engineering, the geometry of a large number of structural details may involve the combination of straight and curved parts in order to meet requirements of functionality andlor attractive design. Piping systems are structural elements used in the chemical industry, aeronautical and aerospace engineering, conventional and nuclear power plants and fluid transport in general-purpose process equipment. This paper presents a new finite element pipe with 19 degrees of freedom, where shape functions are set-up from the displacement field parallel to a local reference system. A displacement-based formulation was developed with Fourier series for incr
