ASTM A1085

ASTM A1085 is a new HSS specification designed with enhanced performance. This critical improvement makes HSS design easier and more effective for dynamically loaded structures. ASTM A1085 was designed for use in applications such as: buildings, bridges, towers, cranes, sign supports and poles, off-shore production and drilling platforms, Roll-Over Protective Structures (ROPS), and Falling-Over Protective Structures (FOPS).

Tighter material tolerances and a single minimum yield stress of 50 ksiMore stringent wall tolerances and the addition of a mass toler-ance mean the full nominal wall thickness can be used for design of HSS. This means no longer needing to reduce the nominal wall thickness by 0.93 as prescribed in the AISC Steel Construction Manual for both member selection and connection design. More area available for design and a higher min yield means that HSS are more economical and more efficient.

Maximum specified yield stress of 70 ksiThe maximum yield will result in a lower expected yield strength and reduce capacity design requirements and column required strengths in seismic designs. This is the only specification used in North America or Europe that limits the maximum yield stress in HSS.

Standard requirement for Charpy notch toughnessNew specification will require all HSS to meet a minimum CVN value of 25 ft-lb @ 40° F, which corresponds to AASHTO Zone 2. Having the minimum CVN required makes HSS more suitable for use in dynamically loaded structures.
