The strength of tubular joint has been an important problem for integrity of steel structures in which many tubular members are used. This paper presents the stress concentration of flared joints which are for setting staight two tubular members with different diameter. Two types of flared joints are treated. One is a normal flared joint between cylindrical tubes (a cyllindrical flared joint). Another is a special flared joint between cylindrial tube and box tube (a cylindrical/box flared joint). The latter joint was developed for semisubmersible rigs. Model test and FEM analysis were performed due to obtain the stress characteristics of these flared joints. Based on the results and the basic equation in AWS code D1.1-81, the equations for estimation of the following SCFs (stress concentration factors) are proposed newly. (1) SCF of a cylindical flared joint with a ring stiffener (2) SCF of a cylindrical/box flared ioint without a ring stiffener (3) SCF of a cylindrical/box flared joint with a ring stiffener
