Comparative Study of Tubular Joint Design Formulas According to API RP 2A WSD 21st Edition and 22nd Edition

Abstract The strength of the jacket substructure on a fixed offshore platform is dictated by tubular connecting leg and braces. accuracy static calculation joint very important to ensure integrity structure during its operation. Therefore, as Recommended Practice, API RP 2A WSD always regularly was updated based results latest research obtain more accurate in analysis joint. This paper discusses difference between simple design 21st Edition 22nd Edition. study will show for types K, T, X. be compared modelling validation. Furthermore, this variables affecting result these two versions which factors considers changing formula. certainly formula editions API, comparison with finite element demonstrates good results.
