| Abstract: | This paper summarizes the study results of the strength of cylindrical legs with square or rectangular cutouts of outer-rounded corner under axial loading for jack-up drilling rigs. Details are presented of the effect of the cutout parameters on stress concentration factors, contact stresses of pin holes and loading capability of legs. Furthermore, the strength criterion of legs has been considered. Owing to their complexity, these problems can not be solved analytically, but by means of photoelastic experiments (normaltemperature photoelastic, frozon and reflection methods), steel model electric-measuring experiments, the finite element calculation and the approximate calculation and analysis, instead. The results obtained can be used for design and calculation of cylindrical legs, and also for evaluation of the design and calculation of the similar structures. |
