Torsional beam analysis subjected to static load on offshore structure deck

Abstract

The jack-up is one of the fixed typical offshore structures consists of many elements such as beams, plates, braces and so on. Those elements play an important role to strengthen the structure locally and globally from internal and external loads. Such kind of loads eventual act on element like beam and make torsionally. This phenomenon must be analyzed because the beam is connected to other element. The objective of the present study is to analyze the torsional beam subjected to static load on offshore structure deck. The jack-up structure particularly beam element located on the deck is selected to be analyzed. Two cases of beam model are taken. The numerical method is performed to analyze the beam. The result obtained by numerical method for two beam model si compared with one another.
