PROJECT DESCRIPTION

FROM THE ARCHITECTS:

The project is located in the 10 thousand peaks area of Xinyi, Guizhou, China, which is aimed to create a now model for future city life with the conception of “Vertical Forest”, and do implementation of eco-urbanization in the continue way. The design will effectively keep the original natural appearance of 10 thousands peak area, to minimize the damage in this eco-space. The design will follow the principle of reservation of the original terrain and characteristics, to creating “forest city” in real. The overall project area is 400 are, and the mountain hotel is the most special resort in the of the design program, the area is 31200 m2. The concept comes from the unique scenic of 10 thousands peak area, together with the combination of terraced structures and the Minorities tribe forms. Relying on the original mountain, hundreds of spaces inside the building arrayed like terraces, as well as crescent moon holding and integrating the hill. The façade uses the concept of “vertical forest” along with multiple trees, which hide the building inside peaks and echo with local Karst topography.

Innovative Detail: Wood Innovation and Design Centre

Michael Green Architecture has designed the world’s tallest, modern timber structure for the city of Prince George, British Columbia.

As of last October, the world’s tallest wood building constructed in modern times, using contemporary techniques, could be found on the campus of the University of Northern British Columbia, in the city of Prince George. The eight-story, 96-foot-tall Wood Innovation and Design Centre (WIDC), designed by Vancouver-based Michael Green Architecture (MGA), sits on a concrete raft slab and contains 51,000 square feet of office and educational space. Leasable office space occupies the top three floors while the lower levels are dedicated to the university’s proposed Master of Engineering in Integrated Wood Design program. At ground level, a double-height, triple-glazed curtainwall with laminated veneer lumber (LVL) mullions connects an interior sheathed entirely in wood to the street outside.

The building was designed to showcase the aesthetic and structural capabilities of lumber in commercial construction. “Twelve years ago, we were waking up to the role of buildings in climate issues,” MGA principal Michael Green says. Contemporary construction is predominantly with steel and concrete—materials whose combined production tally up to 8 percent of the world’s greenhouse gas emissions. But timber, when forested responsibly, can reduce emissions and store carbon, which are the most effective methods to preserve the planet, Green says. “That understanding is something we use in suburban housing—building with 2x4s for example,” he says. “But as the world trends toward urban environments, we need taller buildings that incorporate how we built before steel and concrete were in fashion.” Green cites Japanese temples and Egyptian tombs—tall timber structures that stand for millennia and still function as public space today—as examples of low environmental impact buildings with longevity.

Ema PeterThe eight-story-tall building has a timber post-and-beam structure.

Mass timber construction—a term that encompasses the use of prefabricated wood components such as LVL, cross-laminated timber (CLT), laminated strand lumber (LSL), and glue laminated timber (glulam)—supported two goals of the project. It is strong enough to support the WIDC’s post-and-beam structure and lateral-load resisting system, and it supports an exceptionally long life cycle. The building’s dry construction, which was free of concrete and wet materials, permits the wooden components to be taken apart and reused. Glulam beams, which vary in size based on their location, transfer the structural loads to glulam columns, which are 14 inches by 14½ inches on the ground floor and 12 inches by 11½ inches on the upper floors. This post-and-beam superstructure is secured by 2-millimeter to 16-millimeter glued-in rods and stainless steel washer plates. The beam-to-column connection is made using a proprietary, pre-engineered aluminum dove-tail connector.

Ema PeterThree-, 5-, and 7-ply CLT panels make up the custom, staggered design in the floor and ceiling that hides and shelters all building services.

Four-, 6½-, and 9½-inch-thick CLT panels comprise the walls, stair, and elevator core. Three-, 5-, and 7-ply CLT panels make up the custom, staggered design in the floor and ceiling that hides and shelters all building services, and is fortified by two layers of 13-millimeter plywood and semi-rigid fiberglass board insulation. Carpet and ¼-inch needle-punched polypropylene fiber underlayment provide additional sound insulation on floor planes, while wood slats, fiberglass batt insulation, and acoustic ceiling hangers help insulate ceilings.

Structurlam and Brisco Wood Preservers—both located less than 500 miles southeast of Prince George—supplied the mass timber products, which were made of British Columbian spruce pine fir. “We always work with local manufacturers to elevate the game for high-tech solutions,” Green says.

Currently, the city’s building codes restrict lumber construction to lightweight framing for residential construction up to six stories, and nonresidential buildings up to four stories. The province granted an exemption to the WIDC project. This was crucial to the project’s realization, Green says. “Innovation in other industries doesn’t wait the way construction does,” he says. “Advances in software don’t wait, and climate change and environmental issues can’t wait either.” 

Ema PeterWood finishes and the timber structure were used throughout the exterior and interior of the structure.

Building outside of the existing codes became an opportunity to educate and collaborate. Green partnered with contractor PCL Constructors Westcoastearly on, and worked closely with MGA’s lumber suppliers. Since the building core—including the exit stairs—are constructed from CLT, fire and smoke separation engineering was physically tested and demonstrated for city officials. MGA’s modular design for the WIDC can be used in buildings up to 30 stories. The firm is currently working with a U.S. developer on future timber towers. 

“We wanted to encourage building code officials, developers, and contractors to get excited about this,” Green says. “We wanted to show the world how building [with lumber] will work in the future. With just a 16-month design/build process, I almost can’t believe we pulled it off.”

Highlights

• •
  A method to realize social impact through design is evaluated in a multiple-case study.
• •
  By means of a narrative-based study with experts, we assessed the quality of the design outcomes.
• •
  We discuss both studies as research methodology to assess effect-driven design methods.
• •
  Qualitative assessments of methods help improving their fit with design practice.

The study reported in this paper describes the evaluation of the Social Implication Design (SID) method. This effect-driven design method aims to support designers in designing the influence of design manifestations on behaviour in order to counteract social issues. To study the effectiveness of the method, both a multiple-case study with designers and a narrative-based study with social experts have been executed. Based on our findings we discuss the strengths and weaknesses of the method, and suggest improvements. We conclude this paper by reflecting on our approach as research methodology for assessing effect-driven design methods and argue that qualitative studies, prior to validating design methods quantitatively, will increase the significance of design methodology for design practice.

Abstract

The paper presents a structural analysis by means of an orthotropic damage model of a multi-span masonry railway bridge built in the early years of the 20th century. Its aim is to show how this type of model allows for the current bridge mechanical behaviour under service loads to be assessed and the ultimate load to be forecast. It includes a phase of research on archived documents, an in situ investigation phase, an experimental phase carried out on core samples in the laboratory, and a computation phase. Among the different calculation steps, a simulation of the bridge history is performed in order to consider the current cracked state induced by support settlement. In a following step, the traffic loads are applied to assess the mechanical behaviour of the bridge under service loads up to failure. The mechanical behaviour of masonry is described by means of an original 3D anisotropic damage model able to consider the opening and the progressive reclosing of localized cracks. The model uses homogenized parameters considering the weakness of the stone-mortar interface. It has the capability to use material pre-damage. The calculation determines the crack pattern induced in the bridge by support displacements and loads. The support displacement study consists of an inverse analysis aimed at determining the actual present state of the structure from the cracking pattern observed on the bridge. The methodology highlights the importance of considering the whole history of a masonry structure when assessing the current state.
