Building success with the staggered truss

June 17, 2008

By:

Developed during the 1960s by MIT graduate students, the staggered-truss system avoids the use of interior columns to transfer loads to the foundation; instead, trusses themselves carry the brunt of the load transfers. More than anything, the steel design method has potential to take various hotel, condo, and office-building projects away from other construction materials, like concrete, and that's certainly good news for structural steel fabricators everywhere.

The evolution of precision bending

June 17, 2008

By:

Three decades ago bottoming with penetration, or coining, was the only way to achieve high accuracies on press brakes, and this meant fabricators endured high tooling costs. Over the years precision air bending with CNC hydraulic press brakes using precision-ground tooling evolved to become the dominant forming method in the precision market. However, it took some significant machinery advances to get there.
