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
