INSTRUCTOR:
Heather R. Anesta, P.E., SE, MS, StS2
Purpose and Background
ASCE 7 Wind Chapters 27 and 28 present the Directional and Envelope Procedures for MWFRS Design Wind Pressure. This webinar will review the intent of the Chapter 27 and 28 Part 1 Procedures and outline an approach to determining which Chapter is most applicable or practical for a low-rise building design. While the majority of the webinar will focus on regular-shaped buildings, we will also touch on non-rectangular building shapes. This webinar is useful for engineers of all experience levels, from students to senior designers. Its goal is to help engineers understand the differences and similarities between Chapter 27 and 28 Part 1, as they relate to low-rise buildings.
Primary Discussion Topics
- Review ASCE 7-16 Scope, Conditions, and Limitations of Chapter 27 Part 1 and Chapter 28 Part 1
- Review Main Differences between Chapter 27 Part 1 and Chapter 28 Part 1 from a Designer's Perspective
- Discuss a practical approach for determining if your MWFRS wind design should consider wind pressure coefficients from Chapter 27 or 28.
- Conceptual examples of low-rise buildings and the differential effects of choosing Chapter 27 or 28 for its wind design.
- Review the similarities & differences between Chp 27 & 28 Part 1 for MWFRS.
- Participant interaction and discussion
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Explain the limitations of the ASCE 7 Chapters 27 and 28 Part 1 from a Designer's Perspective.
- Explain the origin and intended application of the MWFRS external pressure coefficients.
- Identify the scope of a designer's engineering judgment for selecting either Chapter 27 or 28 Part 1.
- Aid the attendee to develop a sound approach to applying MWFRS wind pressures to low- rise buildings during the design process.
- Identify common errors when applying MWFRS wind loads low-rise buildings for design purposes.
- Avoid design errors due to misapplication of MWFRS Wind Pressures
- Prevent overdesign of buildings due to misapplication of MWFRS Wind Pressures on low-rise buildings.
- Explain the similarities & differences between Chp 27 & 28 Part 1 for MWFRS from Designer Perspective.
- Explain the background testing which informed the wind procedures for Chapter 27 & 28 Part 1.
- Reduce cost and increase efficiency of structural design by better understanding the origin of the external pressure coefficients.
Assessment of Learning Outcomes
Achievement of the learning outcomes by attendees will be assessed through online discussion and case studies. A short post-assessment (true-false, multiple choice and fill in the blank questions) will also be administered.
