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.

1. Understand how to analyze wall framing as part of the MWFRS per ASCE 7-10
2. Understand why wall framing is analyzed using out of plane C&C wind pressures independent of gravity loads
3. Be familiar with various ASCE 7-10 ASD load combinations used for bearing walls
4. Be knowledgeable of standards including the 2015 NDS, 2015 WFCM, and ASCE 7-10 used for design of tall walls

AWC's 2015 Special Design Provisions for Wind and Seismic (SDPWS) is referenced in the 2015 International Building Code (IBC) for design of structures using wood shear walls and diaphragms to resist wind and seismic lateral loads. Provisions in the SDPWS contain the equal deflection requirement for distribution of shear to shear walls in a line which can be met either by calculation of shear wall deflections or use of reduced design unit shear strength. This course will discuss the 2015 SDPWS provisions for distributing shear using the deflection calculation approach and effects on calculated design shear capacity of a shear wall line. It will be compared to the adjustment factor approach which permits distribution of shear in proportion to strength where reduced strengths are determined by use of the 2b_s/h factor for wood structural panels. Allowable stress design (ASD) examples, excerpted from the 2015 SDPWS Commentary are included.

Learning Objectives: 

1. Be able to understand the 2015 SDPWS provisions for distribution of shear to shear walls in a line
2. Be familiar with the 2015 SDPWS provisions for shear distribution based on either i) deflection calculation, or ii) use of reduced shear strengths in accordance with the 2bs/h factor for wood structural panels

This presentation provides an overview of the Force Transfer Around Openings (FTAO) shear wall design approach, recent research in this area, and a side-by-side comparison of design results between segmented, perforated, and FTAO design methods. This methodology is based on a joint research project of APA – The Engineered Wood Association, University of British Columbia (UBC), and USDA Forest Products Laboratory that examined variations of shear walls with code-allowable openings. The study evaluated internal forces generated during testing and assessed the effects of opening sizes, full-height pier sizes, and different construction techniques, including the segmented, perforated, and FTAO methods. Asymmetric piers, multiple openings, and C-shaped sheathing were investigated and rational design methodologies in accordance with the International Building Code have been created.

Learning Objectives:

1. Participants will investigate past and current methods for determining force transfer around openings for wood shear walls through discussion of the joint research project of APA – The Engineered Wood Association, the University of British Columbia (UBC), and the USDA Forest Products Laboratory (FPL).
2. Participants will compare the effects of different opening sizes, full-height pier sizes, and their relationships to the three industry shear wall approaches by illustrating use of the segmented, perforated, and FTAO methods.
3. Participants will observe how the study examined internal forces generated during loading by reviewing full-scale wall test data as well as analytical modeling performed in determining statistical accuracy.
4. Participants will conclude that research results obtained from this study can be used to support different design methodologies in estimating forces around openings accurately.

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 will be presented in addition to the resulting proposals, developed by Committee consensus and submitted to the ICC Code Development Process. The changes were submitted to ICC in accordance with the January 8, 2018 deadline and will be considered during Committee Action Hearings from April 15 – 25, 2018.

Learning Objectives: 

1. Identify the make-up of the TWB Ad Hoc Committee and the process used to reach consensus on proposed code changes.
