Qustis & Answers

TYPICAL ENGINEERING QUESTIONS ASKED ABOUT THE SteelMaster ROOFING SYSTEM:

Question: How does the SteelMaster arch support loads?
Answer: Heavy gauge GalvalumeTM steel fabricated with a deep curved corrugation, designed to safely resist environmental loads through a combination of internal axial forces and bending moments.

Question: Does the SteelMaster Roofing System act as a beam or an arch?
Answer: When interior support is to be used, SteelMaster arches can be designed as curved continuous beams eliminating the horizontal reactions. For longer clear spans, the arches carry loads through a combination of thrust and bending. For shorter clear spans, thrust may be ignored.

Question: What if interior supports are not being used?
Answer: When interior support is not utilized, SteelMaster arches are configured as arches (with combined axial force and bending), not as curved beams.

Question: Does the SteelMaster Roofing System act as a diaphragm? If so how is it achieved?
Answer: Yes. With channel sections connected to the arch panels at the endwall columns, the SteelMaster Roofing System may be regarded as a rigid curved diaphragm for loading transfer purposes.

Question: Can point loads be applied to the system?
Answer: Yes. SteelMaster has designed the roofing section with a 10 psf collateral load. Heavier equipment loads may be spread out over the steel arch sections. Exact allowable point loads will change with different snow loads on the roof.

Question: What kind of modeling assumptions can I use in modeling the SteelMaster Roofing System?
Answer: Structural Engineers may regard the SteelMaster Roofing System as a rigid diaphragm for the support of end walls and load transfers.
