Brad Fletcher, structural engineer at Atlas Tube, explains why you should think about using A1085 HSS when designing structures with seismic requirements. Designing structures for seismic applications can be challenging, especially if you’re designing with A500 HSS. But if you design your structure with A1085 HSS, you’ll know the expected strength and the full nominal section properties, allowing you to easily predict performance. It’s time to think differently about designing for seismic applications with hollow structural sections. It’s time for ASTM A1085 HSS.
