One of American Wood Council’s most commonly downloaded publications is the Prescriptive Residential Wood Deck Construction Guide (DCA6). This presentation provides a deck experts perspective on deck construction which is not included in DCA6. One of the leading contributors to exterior deck collapses is decay of the supporting structure - namely the rim joist of the house - due to poorly detailed or damaged deck ledger flashing. This program will examine a step-by-step flashing process that protects the wall behind the ledger and flashes over the top to block and redirect water onto the face of the ledger and cladding at three critical areas. A flashing approach to seal cantilevering deck / balcony joists where it penetrates through an exterior wall and WRB will also be examined.

Also discussed are solutions to address critical deck stair support, connections, construction and safety details: specific attention to the top of a stairway to the deck; the required footing at the base of a stairway; stairway landings; riser openings and stabilizing the bottom stairway guard post.

Learning Objectives: 

1. Describe a redundant ledger flashing system that reduces the chance water leakage into the wall assembly of the dwelling.
2. Identify IRC provisions for deck ledger flashing and label the layers of a ledger flashing system.
3. Differentiate between decks that require stairway footings that extend below frost line from decks that do not require frost-depth footings.
4. Describe common issues with deck stairway to deck frame attachments.

Proper design of wood structures to resist high wind loads requires the correct use of wind load provisions and member design properties. A thorough understanding of the interaction between wind loads and material properties is important in the design process. Adjustments from reference wind conditions to extreme-value peak gusts require designers to make similar adjustments to design properties to ensure equivalent and economic designs. Wind load provisions have been developed for design of major structural elements using Main Wind-Force Resisting System (MWFRS) loads and secondary cladding elements using Component & Cladding (C&C) loads. Elements and subassemblies which receive loads both directly and as part of the main wind force resisting system, such as wall studs, must be checked independently for MWFRS loads and C&C loads. A load bearing stud wall design example based on the allowable stress design methods outlined in AWC's 2015 National Design Specification® (NDS®) for Wood Construction and 2015 Wood Frame Construction Manual along with ASCE 7-10 Minimum Design Loads for Buildings and Other Structures will demonstrate standard design checks for limit states of strength and deflection.

Even before cross-laminated timber (CLT) was recognized in the 2015 IBC, there was growing interest to use it in the US by designers seeking a sustainable construction product, with a reduced on-site construction time, all while exploiting the natural beauty of wood to provide a pleasing environment to occupants. Not only does CLT meet all of these attributes, but it also provides excellent thermal separation and can be designed to provide up to two hours of fire resistance and even more when protected. This presentation will provide a step-by-step design example of CLT used in a wall application to resist gravity loads as well as design for exposure to fire per the 2018 National Design Specification® (NDS®) for Wood Construction and AWC’s TR-10 – Calculating the Fire Resistance of Wood Members and Assemblies.

Learning Objectives: 

1. Discuss relevant CLT product manufacturing and design standards and identify where these standards are referenced in the IBC.
2. Describe how to design CLT walls for gravity loads.
3. Design a CLT wall for fire resistance and thermal separation.
4. Discuss existing state of in-plane CLT shear wall design provisions.

Cross-laminated timber (CLT) has been in use worldwide for over 15 years, but most notably in Europe. Building with CLT has increased in popularity for many reasons including: just-in-time fabrication and job site delivery, speed and efficiency in construction, reduced job site noise and on-site labor force, substitution of high embodied materials with a renewable resource that sequesters carbon, and creating a living or work space that has the aesthetics of exposed wood.

The recent introduction of CLT in the 2015 National Design Specification® for Wood Construction (NDS®) and the 2015 International Building Code has opened up an exciting new chapter in wood construction. The use of CLT alone or in combination with other mass timber elements, such as glued laminated timber (GLT), nail laminated timber (NLT), or structural composite lumber (SCL), is becoming more common in buildings complying with the current code. There is also an effort underway by the International Code Council (ICC) to recognize the use of mass timber elements in taller, combustible construction through the work of the ICC Tall Wood Ad Hoc Committee. This presentation will provide an introduction to CLT including relevant design standards and code references. Examples of various mass timber buildings around the world will be provided and potential future code provisions relating to mass timber will also be discussed.

Learning Objectives: 

1. Be able to define cross-laminated timber
2. Be aware of code and standard updates relevant to CLT and other mass timber elements
3. Be aware of notable mass timber structures around the globe
4. Learn about current tall wood building projects and resources

In early 2016, the ICC Board of Directors approved the creation of an ad hoc committee to explore the building science of tall wood buildings with the scope being to investigate the feasibility of and take action to develop code changes for tall wood buildings. Since that time, the Tall Wood Building (TWB) Ad Hoc Committee has reviewed voluminous materials regarding tall wood buildings, including results of various testing around the world, as well as studies domestically in support of the TWB charge to conduct a thorough review of the science of tall wood. The TWB developed its own test scenario(s) to substantiate any code change proposals (testing was carried out at ATF labs); and worked to develop a comprehensive set of technically-substantiated code changes for consideration during the 2018 Group A code development process. The intensive research performed by the Committee was submitted under the ICC Code Development Process, along with the resulting proposals developed by Committee consensus. All of the Group A TWB proposals have been approved. The TWB has also developed a set of Group B proposals, submitted in January 2019.

Learning Objectives: 

1. Identify the make-up of the TWB Ad Hoc Committee and the process used to reach consensus on proposed code changes.
2. Recognize how the new types of construction compare with existing types of construction in the International Building Code and specify the inherent differences and conservative approaches the new types have.
3. Understand the process by which the allowable heights, areas, and number of stories permitted for the proposed mass timber types of construction were developed and will be able to utilize the information for building design.
4. State the fire resistance requirements for mass timber building elements. Further, they will be able to distinguish when and where non-combustible protection can be omitted.
