This paper presents a boundary element methodology for the numerical solution of bolted connections where a clamped plate is a T-flange and there is a flat unstressed surface. The boundary element technique using Melan's solution is particulary well suited to this type of problem and reduces the data preparation necessary to solve the problem with a free flat boundary. In this paper, Melan's solution was briefly examined and the necessary fundamental solutions derived. Then, discussions were made on the distribution of contact stresses and the force ratio (a ratio of an increment of axial tension of a bolt to an external load). The numerical results are in fairly good agreement with the analytical ones obtained by the theory of elasticities.
