WebbFirst, let us review the relevant equations, we have tensile strength by yielding, for which we have Pn=fy*Ag. For the design according to the LRFD, we will multiply by φt, where φt =0.90. If we wish to evaluate by the ASD, then we multiply by 1/ Ωt, for which the value is 1/1.67 in tension. For tensile rupture, we have Pn=fult*Aeff, and in ... Webb• Note 2. Why is the resistance factor (φt) smaller for fracture than for yielding? The smaller resistance factor for fracture (φt = 0.75 as compared to φt = 0.90 for yielding) reflects the more serious nature and consequences of reaching the fracture limit state. • Note 3. What is the design strength of the tension member? 5
