Purpose and Background

This three-part webinar series discusses how to use the wind load provisions of ASCE 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures. The series will cover the basics of wind engineering including the atmospheric and aerodynamic effects of wind on buildings. The changes recently adopted for use in ASCE 7-22 will be a prominent part of the material. The changes include revised procedures for both the Directional and Envelope Methods, changes in external pressure coefficients for roof components and cladding and the addition of pressure coefficients to use for elevated buildings and ground mounted solar arrays.

The series will cover all both primary methods used to develop wind pressures on buildings. Wind pressure determination for both the Main Wind Force Resisting System (MWFRS) and Components and Cladding (C&C) are included.

This webinar is being offered early in the outreach process for ASCE 7-22 to give engineers a chance to get familiar with the new provisions long before their local community adopts a building code that requires the use of these new provisions. Engineers may want to practice the use of these new provisions to determine the real effects on designs and on client requirements. Other engineering tools such as computer software will not likely be available yet that include these changes.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Gain an understanding of how wind interacts with building elements and how building design influences wind pressures
• Examine how to apply the wind load provisions to example buildings
• Learn what the significant changes are in the ASCE 7-22 wind provisions
• Learn how to apply changes in component and cladding loading and how to use provisions for roof and ground mounted solar arrays
• Determine how to apply the wind load provisions in ASCE 7-22 to design situations
• Become acquainted with ASCE 7-22 changes
• Use the wind provisions to solve an engineering problem
• Describe the design issues that must be considered when buildings are not exactly like those used to develop the wind provisions

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

Who Should Attend?

The level of instruction is appropriate for engineers just learning the specific wind provisions of ASCE 7-22 and how to apply those provisions to design situations. The primary audience is structural engineers who have some experience at performing designs for buildings and other structures but have not had much experience with wind design.
