This webinar was co-sponsored by ASCE's Structural Engineering Institute (SEI) and ASCE Continuing Education

Instructor:  Scott Lockyear, P.E.

Course Length: 1 Hour

Purpose and Background

Many lessons have been learned from Hurricane Katrina and Andrew resulting in significant changes to wind design code provisions. This presentation will discuss the various methods available in ASCE 7-05 for calculating wind pressures including the simplified, analytical and wind tunnel methodologies with a focus on practical application. This will include discussion on exposure categories, component and cladding vs. main wind force and limits for each methodology. The latter half of the presentation will look at design concepts that can be utilized to efficiently resist wind loads using a wood frame structure. This includes optimization of diaphragms for given loadings in addition to an analysis of shear wall design methodologies including full height segments, force transfer around openings, and perforated shear wall methodologies. Additionally, methods for resisting uplift loads, including uplift straps, and combined shear/uplift panel resistance will be investigated. Overall, the audience will develop a basic understanding of the latest wind design methodologies and methods to resist loading.

Learning Outcomes

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

• Review two methods for calculating main wind force design pressures
• Discuss how to determine C&C loading
• Discuss wood frame diaphragm and shearwall design
• Investigate design considerations for wall systems

Seminar Benefits

• Learn the difference between shearwalls designed as perforated or for force transfer around openings
• Examine how wood shearwalls can be used to resist shear and uplift forces
• Learn about changes/additions in the latest edition of ASCE 7 wind loading
• Observe design considerations for wood frame tall walls
• Discuss connections of shearwalls and diaphragms
• Investigate wood frame diaphragm design techniques
• Discuss installation issues that have occurred after hurricanes Katrina and Andrew

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).

Intended Audience

This course is designed for engineers from beginner to intermediate experience that are interested in the design of low rise structures to resist wind loads. Emphasis is placed on design using wood frame construction.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
