What is the minimum required end bearing for a steel deck?

The minimum required end bearing for a steel deck is 1-1/2 inches. This specification is critical in structural design to ensure adequate support and stability of the decking system, enabling it to safely transfer loads to the underlying structure. A bearing surface of this size helps to distribute the weight effectively, maintaining the integrity of the deck and preventing potential failures that could occur if the bearing were insufficient.

A bearing of less than the required 1-1/2 inches may not provide the necessary support or could lead to localized stress concentrations that compromise the overall structural performance of the deck. Therefore, adhering to this standard is essential for meeting safety and performance codes in construction practices.
