Ponding Analysis With AISC/SJI Design Guide 40
This educational video explains the fundamentals of roof ponding analysis and rain load requirements in ASCE/SEI 7-22. Mark Denavit, Consulting Engineer for SJI and Associate Professor at the University of Tennessee, Knoxville, discusses static head, hydraulic head, and ponding head, and demonstrates how iterative ponding analysis is performed using guidance from AISC/SJI Design Guide 40.
The video also highlights the SJI Roof Bay Analysis Tool, which automates ponding analysis and provides design checks for steel joist and structural steel roof systems.
Topics covered include:
- SJI Roof Bay Analysis Tool features
- Rain loads in ASCE/SEI 7-22
- Ponding analysis concepts
- Iterative structural analysis
- Roof deflection effects
Design Guide 40 Rain Loads and Ponding
Developed by AISC and SJI, Design Guide 40 provides a comprehensive review of rain loads and ponding effects on roofs constructed with structural steel, steel joists and joist girders.
It also includes recommended methods of analysis and design accounting for ponding effects as well as details on the SJI Roof Bay Analysis Tool – With Ponding Analysis.
Roof Bay Analysis Tool – With Ponding
Developed by the Steel Joist Institute to assist the structural engineer of record (SER) with selecting optimal bay sizes and framing options, this tool provides a number of input options, allowing for customization based on project criteria, designer preference, and owner and code requirements. It also includes a ponding analysis option to assist in proper evaluation of loading conditions.
