Erol Karacabeyli, Mohammad Mohammad
Wood is a natural and renewable building material that has long been preferred for its high strength-to-weight ration, ease of assembly and availability. Timber structures from ancient times far surpass current limitations set by many of the modern building codes worldwide. Recently, the international architecture, engineering, and construction industries have developed renewed interest in specifying and using wood in multi-story buildings mainly due to its aesthetics, versatility, environmental...

Tall Wood Structures: Fire-Resistance Design Primer for Mass Timber
https://www.awc.org/pdf/education/des/AWC-DES602-1... [Tall Buildings] [Presentation] 2018
James Smith
This presentation examines how fire resistance ratings in the 2015 International Building Code (IBC) apply to mass timber and heavy timber construction. Topics include how the IBC incorporates fire testing and calculation methods to quantify fire resistance as well as how various materials, including wood, behave when exposed to high temperatures in fires. Discussion will include code compliant calculation methods for fire resistance ratings of wood frame assemblies and for wood members exposed ...

Heavy timber construction (Type IV in the International Building Code) is one of the oldest building types used in the United States. There are efforts by underway to expand the use of heavy timber construction through the International Code Council (ICC) Ad-hoc Committee on Tall Wood Buildings (TWB) utilizing mass timber construction. This article covers a brief history of heavy timber construction and the progress of the TWB that researched tall mass timber construction and performed testing t...

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 the 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 ch...

Cross-laminated Timber: New projects show how the material is fulfilling 'tall' orders
https://www.awc.org/pdf/education/des/AWC-DES611A-... [Tall Buildings] [Magazine/Newspaper Article] 2017
Kenneth E. Bland
Modern-day technologies and product delivery methods have created a bold new opportunity for wood products, which in turn has given rise to a new category of structural framing systems using mass timber. The possibility of tall wood buildings represents the first significant challenge to concrete and steel structures since their inception in high-rise building design more than a century ago. Cross-laminated timber (CLT) is among the products helping drive this trend. ...

Michelle Kam-Biron, Lori Koch
This presentation will focus on Nail-laminated Timber (NLT), Glued-laminated Timber (GLT) and Cross-laminated Timber (CLT) structural framing members. NLT and GLT has been adopted in the IBC and utilized throughout the world for several decades on a wide variety of buildings. Often selected for aesthetic reasons or its unparalleled design flexibility, both offer superior structural performance combined with long term durability. CLT has been recently incorporated in AWC's National Design Specifi...

Chadwick Dearing Oliver, Nedal T. Nassar, Bruce R. Lippke, James B. McCarter
Life-cycle analyses, energy analyses, and a range of utilization efficiencies were developed to determine the carbon dioxide (CO2) and fossil fuel (FF) saved by various solid wood products, wood energy, and unharvested forests. Some products proved very efficient in CO2 and FF savings, while others did not. Not considering forest regrowth after harvest or burning if not harvested, efficient products save much more CO2 than the standing forest; but wood used only for energy generally saves slight...

Can Wood Become an Alternative Material for Tall Building Construction?
https://ascelibrary.org/doi/pdf/10.1061/%28ASCE%29... [Tall Buildings] [Journal Article] 2017
Jamshid Mohammadi, Lei Ling
With a growing interest in using timber as a structural material for tall buildings in response to trends in sustainable design, several timber buildings between 7 and 10 stories have been built in Europe and Australia. However, in the United States, timber buildings are still limited to 6 or fewer stories. The availability of glued laminated timber enables the fabrication of structural members with cross-section sizes and shapes capable of supporting heavy loads. Although this may be appealing ...

Cross-Laminated Timber for Single-Family Residential Construction: Comparative Cost Study

Brad Burback, Shiling Pei
Cross-laminated timber (CLT) has emerged in recent years to become a widely recognized mass timber product for large-scale wood construction projects. The advantage of large CLT buildings has been recognized by investors and the public, resulting in a number of tall wood buildings around the world. It is generally believed that newly constructed CLT buildings can be cost competitive against steel and concrete options in certain scenarios. However, the cost-effectiveness of CLT in single-family r...

Cross laminated timber (CLT): Design approaches for dowel-type fasteners and connections

Andreas Ringhofer, Reinhard Brandner. Hans Joachim Blab
Within the last 20 years, cross laminated timber (CLT) has become one of the most important building products in contemporary timber engineering. By the end of this decade, its annual worldwide production volume is expected to exceed 1,000,000 m3. The industry, engineers, architects and constructors have a strong interest in implementing CLT in European product, design and execution standards. The design of CLT is part of the currently ongoing revision of Eurocode 5. In this context and in addit...
