About this detail

This structural detail specifies the properties and attachment requirements for a twenty gauge, one and one-half inch deep Type B steel roof deck with a yield strength of fifty ksi. The assembly requires a sheared side lap connection at twenty-four inches on center maximum, utilizing proprietary connections such as Punchlok or Deltagrip. Each support requires a minimum of five one-half inch diameter effective puddle welds across the thirty-six inch panel width. Supports parallel to corrugations require puddle welds spaced at twenty-four inches on center maximum. Section properties list a moment of inertia of .219 inches to the fourth per foot and section moduli of .230 and .237 inches to the third per foot. A heavier gage or weld pattern must be provided as required to develop diaphragm shears.
