This presentation introduces basic design and construction methods for single-story residential wood decks focusing on the significant changes to the 2021 International Residential Code (IRC). The vertical and lateral load paths of conventional residential decks, as well as other general information about decks is also included. Specific design guidance includes convenient span tables for joists and beams and tables of post sizing limitations and connection methods.
Fire-Resistance and Sound Ratings for Wood Frame Assemblies
Building height, area, occupancy class, and number of stories will often determine the fire resistive construction requirements of building elements in light wood frame construction. This presentation introduces requirements for fire resistance and sound transmission in wood frame buildings of Types III and V construction. One of the methods for determining fire resistance in the International Building Code (IBC) is fire-resistant designs documented in approved sources. The American Wood Council Design for Code Acceptance No. 3 Fire Resistance-Rated Wood-Frame Wall and Floor/Ceiling Assemblies (DCA3), is commonly used as an approved source to specify fire-resistance-rated wood frame assemblies. The DCA3 can also be used to demonstrate compliance with sound transmission requirements.
Safeguarding Buildings During Construction: Fire & Life Safety Best Practices
This program provides information to assist the Fire Service charged with responsibilities for fire and life safety on a construction site to follow best practices. Builders and building officials will also benefit from the information provided. The purpose is to reduce the risk of injuries and losses from fire. The information applies to the design and planning stages as well as the actual construction phase of buildings. Many hazards can be addressed before they become an issue by adoption of best practices and rigorous code enforcement. The primary focus of this program is on large buildings during construction. Other topics that include demolition, alterations, renovations, repair and maintenance, as well as newly completed buildings will be discussed. This program provides guidance that is based on compliance with Chapter 33 of the 2021 International Fire Code, Chapter 33 of the 2021 International Building Code, and NFPA Standards 1 and 241.
An Introduction to Mass Timber Buildings in the IBC
This presentation will introduce learners to new Mass Timber buildings (Construction Types IV-A, IV-B, and IV-C). The criteria and products commonly associated with Mass Timber buildings will be discussed. The course will provide an overview of the work of the International Code Council’s (ICC) Tall Wood Building Ad Hoc Committee (TWBAH). The presentation will provide an overview of fire tests performed in support of these changes. Allowable heights and maximum number of stories permitted for the new Mass Timber Construction Types will be discussed, along with the basis for determining required fire resistance, and the importance of non-combustible protection.
Essential Code Compliance in Light Wood Frame Construction
Three building features - height, area, and number of stories - will often determine the fire resistive construction requirements of building elements in light wood frame construction. This presentation introduces common types of framing and scoping requirements associated with using wood in combustible construction in Types III and V structures. These requirements are summarized in the 2018 Code Conforming Wood Design (CCWD) which will also be discussed. Additionally, one of the methods for determining fire resistance per section 703.3 in the International Building Code is fire-resistant designs documented in approved sources. The American Wood Council's Design for Code Acceptance No. 3 Fire-Resistance-Rated Wood-Frame Wall and Floor/Ceiling Assemblies (DCA-3) is commonly used as an approved source to specify rated wood-frame assemblies.
Based on the popular Code Conforming Wood Design (CCWD), a joint publication of the American Wood Council (AWC) and the International Code Council (ICC), this presentation concisely summarizes the 2018 International Building Code (IBC) for commercial and multi-family residential construction. It will explain the determination of maximum building size for eight common use groups using the height and area tables of the 2018 IBC and pre-calculated tables provided in the CCWD. It will also address establishing fire resistance for wood assemblies and heavy timber; special provisions for pedestal buildings; criteria for finishes, appendages, and other wood features; the scoping of referenced wood design standards; an overview of structural provisions in Chapter 23; and requirements for precautions during construction.
This course introduces basic design and construction methods for single-story residential wood decks focusing on the significant changes for the 2018 IRC. The vertical and lateral load paths of conventional residential decks are addressed in the 2018 International Residential Code. Specific design guidance includes convenient span tables for joists and beams and charts of post sizing limitations and connection methods. Figures for multiple lateral connections make connection to an existing dwelling simpler and require less removal of existing materials.
This presentation will provide an overview of the significant changes for wood design per AWC's National Design Specification® (NDS) for Wood Construction. The NDS is referenced in the International Building Code and International Residential Code and used to design wood structures worldwide. The 2018 NDS references ASCE/SEI Standard 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures which includes increased wind loads. Participants will learn about changes in the 2018 NDS to address increased wind loads and gain an overview of the standard.
The Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings (ANSI/AWC WFCM-2018) has been updated and is referenced in the 2018 International Building Code (IBC) and 2018 International Residential Code (IRC). The 2018 WFCM uses gravity and lateral loads based on ASCE 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures. This presentation will provide an overview of the significant changes in the 2018 WFCM relative to the previous 2015 edition. The WFCM provides code officials and designers with time-saving tools based on engineered and prescriptive solutions (based on structural engineering principles) for wood structures to resist anticipated lateral and gravity loads.
A Brief Introduction to Wood Material Science: Wood as a Structural Engineering Material
The material science of wood influences its behavior from harvest through the use phase and beyond. This course will provide an introduction to the material science of wood, wood-moisture relations, and wood anatomy. The types of wood products structural engineers may use in designs, and the standards governing these products are also discussed.
Advancing Environmental Transparency for Wood Products
The built environment is responsible for nearly 40% of annual global greenhouse gas emissions. In order to avoid the worst climate change scenarios, rapid decarbonization is needed in all sectors. Wood products present a right-now solution to this challenge, as they are significantly lower in embodied carbon than other conventional building materials, and, when sourced from sustainably managed forests, provide numerous environmental benefits. This webinar will walk through the sustainability story of U.S. wood products and show the work we’re doing to tell the story transparently through data and EPDs.
Answering Your Deck Questions: A Panel Discussion With The Pros
Do you have questions on deck design? Now’s the chance to ask the pros! Renowned deck expert Mike Guertin joins AWC’s Matt Hunter, BCO, and Loren Ross, PE for a panel discussion on all things deck construction. Topics covered will include relevant International Residential Code (IRC) references, AWC’s Design for Code Acceptance 6 (DCA6) – Prescriptive Residential Deck Construction Guide, and other relevant documents. Attendees are asked to come prepared with plenty of questions – in this new panel discussion format we are encouraging participants to engage with our experts and help guide the discussion!
By the end of this learning unit, you will be able to:
Discuss deck load path code requirements and how to satisfy them.
Recognize proper design and detailing of significant components.
Identify best construction practices outlined in DCA6s.
Indicate relevant analysis requirements and code updates.
