  1. What modulus of elasticity is typically used for structural steel in U.S. design practice?

    Answer: 29,000 ksi

    AISC specifies E = 29,000 ksi for structural steel regardless of grade.

  2. What are the minimum specified yield and tensile strengths of ASTM A992 steel used for wide-flange shapes?

    Answer: Fy = 50 ksi, Fu = 65 ksi

    A992 is the standard W-shape grade with Fy = 50 ksi and Fu = 65 ksi.

  3. What is the approximate Poisson's ratio of structural steel in the elastic range?

    Answer: 0.30

    Steel has a Poisson's ratio of about 0.3 in the elastic range.

  4. What is the approximate coefficient of thermal expansion of structural steel?

    Answer: 6.5 × 10⁻⁶ per °F

    Steel expands about 6.5 × 10⁻⁶ in/in per °F, close to concrete, which is why reinforced concrete works under temperature changes.

  5. Which tensile test result is most commonly used as a measure of a steel's ductility?

    Answer: Percent elongation at fracture

    Percent elongation over a gauge length shows how much plastic deformation the steel can take before it fractures.

  6. Which test is commonly specified to evaluate the notch toughness of structural steel at low service temperatures?

    Answer: Charpy V-notch impact test

    The Charpy V-notch test measures the energy a notched specimen absorbs on impact at a specified temperature.

  7. Which statement about fatigue behavior is correct?

    Answer: Steel generally has an endurance limit below which it can take an essentially unlimited number of cycles, while aluminum does not

    Ferrous metals' S-N curves level off at an endurance limit, but aluminum's S-N curve keeps going down.
