Engineer FAQ:
Does the system support ASD and LRFD? Yes. Both ASD (AISC 9th Edition) and LRFD (AISC 14th Edition) are supported.
Is there a building height limit? No. Girder-Slab® can be built as high as any other structural steel building.
How does fabrication work? The D-Beam® is fabricated by the project's local steel fabricator via standard competitive bid — no sole-source supplier required.
What fire ratings are available? UL K912 under ANSI/UL 263 (US) and CAN/ULC-S101 (Canada). Restrained: 2-hour and 3-hour. Unrestrained: 2-hour.
What testing has been conducted? Structural load testing at Villanova University and Auburn University — above code-required residential live loads.
