    Steel Material Properties

    V-Star 50 is a Bethlehem Steel alloy it looks like http://asmcommunity.asminternational.org/portal/site/www/AsmStore/ProductDetails/?vgnextoid=6c48611a9a5de110VgnVCM100000701e010aRCRD

    Evaporation measurment

    I would suggest something more emperical. You're not going to get a very accurate evaporation figure for your short term test using a complex method that will likely require a number of assumptions, and it sounds like accuracy is fairly important. I spent some time trying to design an...

    Bracing Thermal Stresses

    That's not a bad thought. The braces would end at the same node, so thermal lateral loads will mostly cancel out in the steel before they hit the foundation, plus the braces would terminate at an outside column where the tie beam will match some of the deflection. I'll take a closer look at...

    Bracing Thermal Stresses

    I've done up a quick sketch. Unfortunately I'm on a site visit and don't have autocad or a scanner with me, so it's a pretty horrible MSPaint abomination. This anchor bay supports lateral loads from 5 bays to the right applied along the top and one very thin bay to the left applied at the...

    Bracing Thermal Stresses

    Also, a somewhat tangential issue that doesn't really apply to this project, what happens to a tension brace that's been heated up? If a brace has been designed to act in tension and thermal expansion pushes a brace to buckling, it would seem that a large sudden deflection would happen if an...

    Bracing Thermal Stresses

    I'm currently working on a large rack in Northern Canada were temperatures can range from -45 to 35 Celsius. For the most part, the structure is designed to deflect so that it does not induce thermal stresses. However, there needs to be an anchor bay to resist lateral loading. Most people I...
