Purpose and Background

This course focuses on the practical application of the ASCE 7‐16 wind provisions on a variety of building sizes, building frames, and building sites. We will cover 11 different wind engineering problems for hurricane and straight-line winds and one problem for tornado wind loads that will illustrate how to use the ASCE 7 provisions. While the problems are created examples, they illustrate a variety of design conditions that are experienced in the real world of building design. The course also creates site decisions to make, building frame design choices to analyze and cladding, components, equipment, and appurtenances that must be analyzed for wind loads.

Two examples will use balloted provisions that will likely be adopted for ASCE 7‐22 in the use of wind loads for ground mounted solar collectors and for tornado loads on tornado shelters. The examples were selected to offer a variety of design conditions, variations on building flexibility, and complications in building geometry that are not explicitly covered in the standard. The range of examples are intended to expose the user to a broad array of wind design problems.

Benefits and Learning Outcomes

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

• Apply the ASCE 7 wind provisions to real building types and design scenarios.
• Explain differences in building characteristics and how those differences influence the approach to wind design.
• Apply wind provisions for components and cladding, solar collectors, and roof mounted equipment.
• Describe the differences between the directional and envelope procedures and which one should be used in various cases.
• Explain how the building natural frequency influences the wind loads on a building.
• List important wind design parameters needed for building design.
