Steel for cold environments 1

[pba]

Two questions:

We have a project in Russia which will have exposed steelwork and winter temperatures of -45 degree celsius. - What type of steel would you use?

Given the steel grade what special designs/techniques would you use in the connections to ensure that brittle fracture did not occur?

Check for impact test to - 45°C in ASTM A913 or A572.

Thanks MotorVib,

Currently we have suggested low alloy steel to European specification with Charpy impact testing at -45. This should be similar to the ASTM standards.

Part of my reasoning in asking the original question was that AISC 13th Ed does not seem (on a casual read) to contain any design guidance on steel in cold temperatures.

Make sure to provide thermal breaks for any individual steel members which are both inside and outside the building.
