Cross-laminated timber engineering : improvement and application
http://ir.library.oregonstate.edu/concern/graduate... [Tall Buildings] [Thesis/Dissertation] 2014
Anthonie Kramer
The development of cross-laminated timber (CLT) panel technology has opened up new opportunities for wood in tall buildings. Several characteristics including seismic performance and speed of construction have raised interest among designers. As CLT gains acceptance in the industry, alternative structural solutions need to be investigated to improve performance of CLT as a building material. The first study presented is an assessment of the viability of hybrid poplar for use in CLT panels. Hybr...

This study summarizes the environmental performance of prefinished engineered wood flooring using life-cycle inventory (LCI) analysis. Using primary mill data gathered from manufacturers in the eastern United States and applying the methods found in Consortium for Research on Renewable Industrial Materials (CORRIM) Research Guidelines and International Organization of Standardization (ISO) standard for conducting life-cycle assessments, the environmental impacts in making engineered wood floorin...

Numerical Investigation of Seismic Isolation for Tall CLT Buildings
http://www.dissertations.wsu.edu/Thesis/Spring2014... [Seismic Performance] [Thesis/Dissertation] 2014
Vincent Bordry
The increasing concern for structure resiliency in seismic regions has brought up the need for new innovative isolation systems to reduce the accelerations in upper stories and protect the structure from significant damage. The objective of this thesis is to study different configurations of seismic isolation; their effects compare to a non-isolated model are evaluated. The isolators are springs and dampers that connect the stories together. Isolate the first story from the rest of the building ...

PRISM
The new 10,000 square foot Belltown Collective, designed by Robert Hutchison Architecture (RHA), is located on the ground floor and basement level of an early 20th century storefront building at 2231 1st Ave, in what was once Egbert’s furniture showroom. Developers evolution Projects hired RHA to redesign the space. Architect Robert Hutchison explains, “When designing a tenant improvement project, I like to work with the existing space as much as possible.” Two existing load-bearing walls run t...

Bois lamellé-croisé (CLT)

Cecobois
Les panneaux de bois lamellé-croisé (cross-laminated timber, CLT), communément appelés panneaux massifs, ont vu le jour en Autriche et en Allemagne au début des années 1990. En Europe, ce produit est largement utilisé dans la construction résidentielle et la construction non-résidentielle de bâtiments multi-étagés de plus de 4 étages. L immeuble Stathaus de Londres, aussi appelé la Timber Tower, est à ce jour le plus haut bâtiment construit avec ce type de produit (9 étages : 8 étages en bois su...

KLH
The new primary school in Red Lodge, designed by Suffolk County Council architectural department, will replace the existing primary school in Tuddenham. The new school will provide 315 primary places, with the ability to expand by an additional 105 places in the future. The school has been designed with future flexibility in mind and the learning spaces can be adapted to suit the teaching needs and shared activity areas. Sustainability was at the heart of the new school design, with the superstr...

Glulam products, when manufactured with waterproof adhesives and pressure-preservative treatments, can be used in exposed applications such as bridges, utility poles and crossarms, and docks. Glulam beams are used in pedestrian and light vehicular applications, such as stream crossings on golf courses and in parks. They are also used in larger highway and railroad bridges. Designs range from straight girders to soaring arches. In all of these applications, the strength and stiffness of glulam gi...

Shoichi Nakashima, Akihisa Kitamori, Kohei Komatsu, Zeli Que, Hiroshi Isoda
The connectors for the CLT shear wall with drift pin joint were suggested. The wall composed of five layers Japanese cedar CLT, steel connectors and drift pins (diameter d = 16mm). The horizontal shear performances of the walls were evaluated by static experiment and 2D frame analysis. The experimental parameter was number and position of drift pins. Characteristic failure was shear failure on the border of the laminae. There were good agreement on initial stiffness, yield load and second stiffn...

Can Mass-timber Construction Materials Provide Effective Thermal Capacitance in New Homes?
http://www.ibpsa.org/proceedings/asim2012/0113.pdf... [Other] [Conference Paper] 2012
M. Deswsbury, D. Geard, R. Fay
Since Australia s acknowledgement of climate change and its need to reduce greenhouse gas emitting activities, the national construction regulations (BCA and NCC) since 2003 have included residential thermal performance requirements. Initially in 2004 the minimum thermal performance requirements was 4 Stars and in 2010 it became 6 Stars. It is planned during the next decade that the thermal performance regulation will increase to a zero energy requirement. Current policy and regulation developme...
