초록
Most ships and offshore structures are equipped with a variety of pipes, which inevitably contain curved portions. The structural design of these pipes mostly relies on the commercial code, CAESAR‐Ⅱ, which was especially developed for the structural analysis of pipes. This tudy conducted stress analyses of the same pipe unit, including loops, using both CAESAR‐Ⅱ and MSC/NASTRAN, and compared the results to nvestigate the characteristics of CAESAR‐Ⅱ. A parametric study was then conducted of the various design variables of pipe loops using CAESAR‐Ⅱ to draw some useful information about the structural characteristics of the loops.
