Web10 Aug 2024 · Ultimate Tensile Strength. Ultimate tensile strength (or just tensile strength for short) is an important property of materials to determine their mechanical … WebThe comparison between working stress and ultimate strength design methods shows that the ultimate strength method is easier to calculate and reduced the main rebar nearly 50% (7.8 sqin Vs 5.39 sqin) and reduced the beam 20% in width (18" Vs 15"). The only drawback of the ultimate strength method is the actual stresses are not shown.
