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

Instructor:  Scott Breneman, Ph.D., P.E., S.E., M.ASCE

Course Length: 90 Minutes

Purpose and Background

As urban infill and transit-oriented developments become more prevalent across America, many developers and designers are looking to mid-rise wood-frame construction for its combination of density and cost-effectiveness. Intended for engineers who don't have experience with this type of construction, this webinar introduces aspects of engineering, design and detailing particular to wood-frame buildings between four and six stories. Topics include gravity system framing styles, shear wall design, diaphragm analysis, and how fire and life safety code requirements impact structural detailing.

Primary Discussion Topics

• International Building Code size limits on buildings of wood-frame construction
• Strategies to accommodate shrinkage and differential movement
• Gravity system detailing approaches
• Lateral load-resisting system options
• Elevator, stair and mechanical shaft detailing approaches

Learning Outcomes

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

• Consider the IBC prescriptive limits on building size for wood-frame buildings and how to apply these limits to candidate building designs
• Recognize common detailing approaches used across the country for exterior wall-to-floor intersections in multi-story wood structures
• Calculate overall building shrinkage and understand how to minimize and compensate for its effects
• Identify different shear wall design approaches including overturning restraint and deflection calculations

Webinar Benefits

• Apply the IBC limits on building size to wood-frame building designs
• Learn detailing approaches for multi-story load bearing walls
• Gain an understanding of how to estimate shrinkage of wood framing due to moisture content changes
• Understand common approaches to shear wall design
• Apply building code requirements to determine if a diaphragm can be considered flexible or rigid
• Understand code provisions for podium-style building systems
• Locate code-accepted assemblies for fire-resistive structural framing systems

Webinar Outline

• Introduction to allowances for wood construction in mid-rise buildings in the IBC
• Dimensional stability of wood framing and building movement
• Approximate dimensional changes of wood with changes in moisture content
• Wood-frame building zone of movement
• Tools to estimate total movement
• Gravity load system detailing strategies for mid-rise wood buildings
• Bearing wall detailing options
• Platform and semi-balloon framing details
• Lateral load-resisting design approaches for mid-rise wood buildings
• Shear wall design options
• Overturning restraints
• Drift and deflection calculations
• Diaphragm flexibility
• Special podium code provisions and related structural requirements
• Fire resistance requirements impacting structural detailing
• Special exterior wall provisions for construction types III and IV
• Shaft wall provisions
• Source of code accepted assemblies

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

• Structural engineers
• Building officials
• Plan reviewers

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]
