Steel joists and steel deck are used to construct economical pitched roofs. This session will provide designers with details and design guidance to help with this situation. Included will be guidance on designing and detailing pitched diaphragms, and economical hip roof framing details.

Learning objectives:

• Describe the factors which impact sloped seats on steel joists.
• Identify the unique considerations for designing and specifying special profile steel joists.
• Summarize the general concerns with steel deck on sloping roofs, and how to properly specify its support.
• Explain the interaction of uplift and shear in steel roof deck diaphragms, and how diaphragms are affected by hip roofs.
