Temperature histories within a T-shape ship longitudinal frame during face repetitive heating and web line heating is calculated by using the distributions of gas temperature and local heat transfer coefficient identified in the previous report (Osawa N. et al, 2004). Using this temperature histories as thermal body forces, torsional deformation of frame is calculated by thermal-elasto-plastic F.E. analysis. Shell and solid F.E. models are employed in the analysis. The calculated deformation is compared with the measurement one. The calculated deformations both in shell and solid analysis agree well the measured ones. This shows the validity of the proposed thermal and deformation calculation methods.
