LOCAL LOAD STRESSES IN CYLINDRICAL-SHELLS AT PLATE CLIPS

Site personnel have to ascend columns, tanks, etc., and to stand on pl atforms; insulation has to be kept in position to preserve energy; equ ipment has to be lifted on occasions. Quite a number of such loads are small and often simple plate clips are used to fasten ladders, platfo rm and hoisting cables. But sometimes it is desirable to assess quickl y the stresses at such clips. Here we provide some simple but accurate formulae for a wide range of clip/cylinder geometries. These non-dime nsional parameter expressions were developed from a large number of li near elastic FEM analyses. In addition a generally applicable stress l imit is proposed for the local stresses in cylindrical shells at clip points.
