Purpose and Background

ASCE 7’s wind chapters apply to “regular-shaped buildings” as defined in Chapter 26 and its commentary. Engineering judgment is required for other building shapes, such as T, L, and U plan shapes, multi-ridge/hip/gable roof systems, and/or single or multi-level roofs. There is no one wind resource which describes how to address non-rectangular low-rise buildings. This webinar will review available wind load concepts, studies, advice from wind experts, and design examples related to wind loading of nonuniform building shapes. It will also outline current and future efforts to provide one holistic approach to non-rectangular low-rise buildings in ASCE 7 wind Chapters, as well as offer attendees the opportunity to share their design approaches. This webinar is useful for engineers of all experience levels, from students to senior designers. Its goal is to help engineers establish a sound basis for their engineering judgment.

Primary Discussion Topics

• Real-world examples of non-rectangular, low-rise building shapes.
• Example applications of MWFRS and C&C Wind Load on non-rectangular, low-rise buildings shapes.
• Review of published literature which addresses wind load application of nonuniform, low- rise buildings.
• Review of the inscribed Method and Separate Structures Methods.
• Full wind load application example of a non-rectangular, low-rise single-family residence.

Webinar Benefits and Learning Outcomes

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

• Explain the limitations of the ASCE 7 Wind Chapters for non-rectangular, low-rise buildings
• Explain the origin and intended application of the MWFRS and C&C external pressure coefficients
• Identify the scope of a designer’s engineering judgment for non-rectangular, low-rise buildings
• Develop a sound approach to applying MWFRS and C&C wind loads to nonuniform, low- rise buildings
• Identify common errors when applying wind loads to nonuniform, low-rise buildings
• Avoid design errors due to misapplication of wind load on nonuniform, low-rise buildings
• Prevent building failure due to misapplication of wind load on nonuniform, low-rise buildings
• Identify the extent of engineering judgment utilized during wind design of nonuniform, low-rise buildings.
