1 The ratio of span of deck unit to average length of sheet is taken to be 1/3.
2 Diaphragm loads are based on steel decks having an average ultimate tensile strength of 55 ksi.
3 Values shown calculated in accordance with SDI equations using a φ factor of 0.5 for LSD for all load conditions.
Note: Reference pages 40-41 for generally higher diaphragm capacities with Hilti Sidelap Connectors (SLC).
