August 19 – New Methods for Ponding Analysis of Open Web Steel Joist Roofs


SKU: Webinar_Aug_2020. Category: .

Product Description

This webinar reviews requirements for rain loads and ponding on open web steel joist roofs and how the recently improved SJI Roof Bay Analysis Tool helps to meet those requirements. Relevant requirements are spread across many documents including the SJI Specifications, ASCE 7, the International Building Code, the International Plumbing Code, FM Global Data Sheet 1-54 and the AISC Specification. A key requirement from ASCE 7 is that bays of roofs that are susceptible to ponding shall be investigated by structural analysis to ensure that they possess adequate stiffness to preclude progressive deflection (i.e., instability) and adequate strength to resist the additional ponding load. The direct analysis method for ponding, described in SJI Technical Digest 3, is a new method for performing such an investigation. This method is implemented within the SJI Roof Bay Analysis Tool, allowing engineers to easily perform these sophisticated analyses while also identifying the most economical roof bay configuration. Recent updates have expanded the scope of the tool to include structural steel beams and girders. Several examples will be presented with comparisons to traditional methods of assessment defined within the AISC Specification.

This webinar is provided by the Steel Joist Institute. Participants can earn 1.5 PDHs.

Learning Objectives

  • At the conclusion of this webinar, participants will be able to recall the main roof ponding requirements from design standards
  • At the conclusion of this webinar, participants will be able to describe the limitations of the method of ponding analysis given in Appendix 2 of the AISC Specification
  • At the conclusion of this webinar, participants will be able to investigate the stability of simple roof systems for ponding using the SJI Roof Bay Analysis Tool
  • At the conclusion of this webinar, participants will be able to identify the main factors influencing the ponding stability of open-web steel joist roofs

Who Should Attend This Webinar?

Structural engineers, fabricators, detailers and connection design firms that are responsible for steel joist and Joist Girder building designs and their connections. Those with very little design experience as well as those with many years of experience will find the course beneficial.
