Moisture monitoring and modeling of mass-timber building systems

The use of mass timber structural products in tall building applications (6–20 stories) is becoming more common around the world including North America. A potential concern is the environmental wetting of mass timber products during construction because such products may dry out more slowly than light-frame structural lumber, and wood, as an organic material, is susceptible to deterioration at ...

Developing seismic performance factors for cross laminated timber in the United States

This paper presents recent progress in the development of seismic performance factors for cross-laminated timber (CLT) systems in the United States. A brief overview of some of other systematic studies conducted in Europe, North America, and Japan is also provided. The FEMA P695 methodology is briefly described and selected results from connector testing and CLT wall testing are discussed. Shear a...

Systematic experimental investigation to support the development of seismic performance factors for cross laminated timber shear wall systems

In the US, codified seismic design procedure requires the use of seismic performance factors which are currently not available for CLT shear wall systems. The study presented herein focuses on the determination of seismic design factors for CLT shear walls in platform type construction using the FEMA P-695 process. Results from the study will be proposed for implementation in the seismic design co...

Ongoing field evaluation of Douglas-fir cross-laminated timber in a ground proximity protected test in Mississippi

Current design standards incorporate the use of preservative treated and naturally durable wood where conditions are suitable for deterioration, but treatment options for mass timber products, particularly, cross laminated timber (CLT) remain to be addressed. Termiticide treatment is a necessity for CLT structures, especially in southeastern climates. Wood species currently used to fabricate CLT a...

Evaluation of cross-laminated timber resistance to termite attack

Cross laminated timber (CLT) is a relatively recent addition to the North American timber construction market. CLT has been successfully used for construction in Europe and, in the past few years, manufacturers have looked forward to expanding the use of this product into the North American market. However, no termite susceptibility experiments have been published for the product and no standards ...

Scotland turns to robotics to help address market needs

A new research program at Robert Gordon University (RGU) will focus on robotic fabrication of cross-laminated timber (CLT) joints. Researchers from the university’s Scott Sutherland School of Architecture & Built Environment will be working on the project with the Construction Scotland Innovation Centre (CSIC) and timber engineering firm Glulam Solution. The aim is to help address housin...

Michigan University to lead the charge in Michigan for CLT

Michigan State University’s future STEM Teaching and Learning Facility will be the first in Michigan to use an innovative wood product for its load-bearing structure. The US$100 million facility will be constructed of glue-laminated wooden columns and cross-laminated timber, or CLT, a relatively new product for the floors and ceilings. Source: Timberbiz “As a leading public research universit...

Woodsolutions SA seminar in timber applications

Timber has been used in various applications from residential housing, marine structures, and more recently mid-rise and multi-storey buildings. However, which species of timber and engineered timber product can be used in the various architectural and structural applications available to those specifying timber? This free South Australian seminar is organised by Woodsolutions and will present...

International accolades for International House

International House in Sydney, the first commercial office building in Australia made from timber, has won a major award at the World Architecture Festival in Amsterdam. The seven-floor structure, which is also the world’s tallest commercial building made from engineered wood, was awarded the Best Use of Certified Timber Prize. The award is supported by PEFC.

AFPA calls for 400,000 hectares of trees to be planted

Changes to the National Construction Code (NCC) will create expanded opportunities for designers, developers and builders to develop innovative mid-rise timber buildings. However, this positive development again reinforces the need for focus on future timber supply and getting more trees planted to ensure demand can be met in coming decades.

New National Construction Code to increase demand for timber products 

The Australian Building Codes Board (ABCB) released the preview version of the 2019 National Construction Code (NCC) that increases the range of buildings, up to an effective height of 25m, in which fire-protected timber construction systems can be used. The new Classes add schools, retail premises, hospitals and aged care facilities to the previously approved multi-residential, hospitality accomm...
