The calculation is intended for the geometrical design and strength control of statically loaded welded connections of machine structures manufactured from carbon steels. Total Bolt Load. Tightening is conducted beyond the yield point and the tightening device is expensive, so it is hard to adopt the same method in the service field. The other assumes that the bolt will stretch and the first few threads (from the head) will assume most of the hold while each successive one from there will have less effect. Eulers Formula Euler analysis applies to slender columns, the formula, for the critical axial concentric load that causes the column to be on the point of collapse for frictionless pinned ends (no bending moment at the ends) is given below. Figure 3 2. We provide a broad range of products including valves, flanges, fittings, tubing and couplings in metric JIS and DIN, and ANSI standards. For DS welds, divide these forces by 2 (the calculations are per unit length of the weld not per unit length of the weld joint).
