I am happy to contact my members here. Yield strength differs in that the bolt or test coupon is pulled to failure, and the yield is calculated (using the 0.2% offset method) along with the tensile, elongation and reduction of area. Since there is a range of values of tensile strength shall we use lower value to calculate thickness 3. @Andy- We are not certain what exactly you are asking. If your structure is rigid enough that it does not wobble about, it will be very strong. With reference to the second number, multiplied by 10, gives the percentage of the first calculation to provide the Yield Strength. In other words, a 3/4 diameter F1554 grade 36 anchor rod will be able to withstand 19,372 pounds force (lbf) without breaking.
