Two AWC standards utilized throughout the nation for a code compliant design of wood shear walls are 2018 Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings and 2015 Special Design Provisions for Wind and Seismic (SDPWS). The WFCM has recently been updated and contains both a prescriptive and engineering design approach. Although the prescriptive design will tend to provide more conservative results than the more efficient engineered design, designers may arrive more readily at a solution. This seminar includes examples of seismic and wind shear wall designs for segmented and perforated shear walls, utilizing the WFCM and the SDPWS along with a comparison of the results. On completion of this course, participants are able to:

The 2018 International Building Code (IBC) specifies that structures using wood-framed shear walls and diaphragms to resist wind, seismic and other lateral loads shall be designed and constructed in accordance with AWC’s 2015 Special Design Provisions for Wind and Seismic (SDPWS). Calculation of wood-frame diaphragm deflection should account for bending and shear deflections, fastener deformation, chord splice slip, and other contributing sources of deflections. The 2015 SDPWS incorporates both a 3-term and 4-term deflection equation that accounts for these variables. This course will provide an overview and comparison of the 3-term and 4-term deflection equations. Additionally, an example showing calculation of mid-span deflection of a blocked wood structural panel diaphragm will be presented.
An overview of 2018 International Building Code (IBC)and 2018 National Design Specification® (NDS®) for Wood Construction provisions related to the use of cross-laminated timber (CLT)will be provided that includes a step-by-step structural and fire design example for a roof and floor application. Additionally, the WoodWorks® Design Office’s Sizer program, version 12 (released January 2019) which enables CLT floor and roof design, will be used to demonstrate the structural design. Innovative wood products such as CLT are leading to a resurgence in heavy timber (Type IV) design and construction. These innovations are also making it possible for wood to be designed and built to taller heights and larger areas than what current codes permit. This has led to code change proposals for the 2021 IBC, expanding Type IV construction for tall “mass timber” buildings. Participants should find this presentation useful for current and future applications utilizing CLT in horizontal assemblies.
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.
This presentation will provide an overview of mass timber which includes any product currently permitted for use in Type IV (heavy timber) construction such as cross-laminated timber (CLT), structural composite lumber (SCL), glued laminated timber (glulam), mechanically laminated decking (aka nail-laminated timber, NLT), and large section sawn timbers. NLT, glulam, SCL, and solid sawn timbers have been adopted in the International Building Code (IBC) and utilized throughout the world for several decades on a wide variety of buildings. CLT was first incorporated in AWC's 2015 National Design Specification® (NDS®) for Wood Construction as well as ICC’s 2015 International Building Code (IBC). All mass timber products offer sustainable qualities as they are manufactured from a renewable resource and store carbon. Structural and fire protection characteristics of mass timber will be discussed as well as IBC code provisions that allow their specification in both residential and commercial applications for a wide variety of occupancies.
1.5 Hours of Education Credit will be available for this course.
Although not defined in the 2015/2018 IBC, this presentation includes an overview of “mass timber” which is any product currently permitted for use in Type IV construction such as cross-laminated timber (CLT), structural composite lumber (SCL), glued laminated timber (glulam), mechanically laminated decking (aka nail-laminated timber, NLT), and large section sawn timbers. This presentation will provide an overview of changes to the 2015 and 2018 International Building Code (IBC) related to mass timber construction. CLT was first incorporated in the 2015 IBC and additional types of SCL were added to Type IV (heavy timber, HT) construction. The 2018 IBC reorganized heavy timber provisions aiding clear application of heavy timber construction requirements while also providing for separate application of code provisions that allow or specify the use of "mass timber" elements outside of Type IV construction.
Changes to the 2021 International Building Code allow for construction of mass timber buildings with larger heights and areas than is currently permitted in Types III, IV, and V construction. This presentation will provide an overview of the allowable heights and areas for the three new types of mass timber construction: Types IV-A, IV-B, and IV-C. Construction fire safety requirements and owner responsibilities related to the fire resistance elements of the building will also be discussed.
