Plyscraper
A plyscraper, or timber tower is a skyscraper made (at least partly) of wood. They may alternatively be known as mass timber buildings. Materials There are four main types of engineered wood used for mass timber including cross-laminated timber (CLT), glued laminated timber (glulam), laminated strand lumber (LSL), and laminated veneer lumber (LVL). Of these three wood systems, CLT is the most commonly used. When other materials, such as concrete or steel, are used in conjunction with engineered wood, these plyscrapers are called “hybrids”. For hybrid buildings, there are some approaches to how different materials can be used including the “Cree’s System” which was developed by Cree Buildings, and the “Finding the Forest Through the Trees" (FFTT) construction model” developed by Michael Green. Cree's System combines the use of concrete and wood mainly in its hybrid flooring systems. In some instances, concrete can also be used as a core or for the foundation of ...

Mass Timber
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, veneers, or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to or more. These products are engineered to precise design specifications, which are tested to meet national or international standards and provide uniformity and predictability in their structural performance. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products.

W350 Project
The W350 Project is a proposed wooden skyscraper in central Tokyo, Japan, announced in 2018. The skyscraper is set to reach a height of 350 meters with 70 floors, which upon its completion will make it the tallest wooden skyscraper, as well as Japan's tallest building. The skyscraper is set to be a mixed-used building including residential, office and retail space. It is scheduled to be completed in 2041, to mark Sumitomo Forestry's 350th anniversary. Proposal The plan calls for the building to be made of 90% wood with the rest being steel. Steel braces will be used to enhance resistance to wind and earthquakes, as the area has high levels of seismic activity. One advantage of wood is that timber-based structures have proven to be very resistant to earthquakes. The project requires 185,000 cubic meters of timber (or 6.5 million cubic feet), and plans to revitalize forestry and timber demand in Japan. The choice of wood, aside from aesthetic and seismic concerns, is part of a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-laminated Timber
Cross-laminated timber (CLT) is a subcategory of engineered wood panel product made from gluing together at least three layers of solid-sawn lumber at angles to each other. It is similar to plywood but with distinctively thicker laminations (or lamellae). The grain of each layer of boards is usually rotated 90 degrees from that of adjacent layers and glued on the wide faces of each board, usually in a symmetric way so that the outer layers have the same orientation. An odd number of layers is most common, but there are configurations with even numbers as well (which are then arranged to give a symmetric configuration). Regular timber is an anisotropic material, meaning that the physical properties change depending on the direction at which the force is applied. By gluing layers of wood at right angles, the panel is able to achieve better structural rigidity in both directions. CLT is distinct from glued laminated timber (known as glulam), which is a product with all laminatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skyscraper
A skyscraper is a tall continuously habitable building having multiple floors. Most modern sources define skyscrapers as being at least or in height, though there is no universally accepted definition, other than being very tall high-rise buildings. Skyscrapers may host offices, hotels, residential spaces, and retail spaces. One common feature of skyscrapers is having a steel frame that supports curtain walls. These curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than those made of reinforced concrete. Modern skyscraper walls are not load-bearing, and most skyscrapers are characterized by large surface areas of windows made possible by steel frames and curtain walls. However, skyscrapers can have curtain walls that mimic conventional walls with a small surfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascent MKE
Ascent MKE is a mass timber hybrid high-rise apartment building in Milwaukee, Wisconsin. The 284-foot (87 meter), 25-story high-rise is the world's tallest mass timber structure, edging out Norway's Mjøstårnet. It features 259 luxury apartments, retail space, an elevated pool with operable window walls, and a sky-deck. In May 2019, Ascent was named a recipient of a U.S. Department of Agriculture grant awarded through the Forest Service's Wood Innovations Grant program. The federal grant assisted with the testing needed to prove mass timber's ability to perform as well as traditional building materials like concrete and steel to meet U.S. building codes. Plans for the project were unveiled in 2018. While the initial design included 21 floors, updates and subsequent approvals brought the total to 25 floors in March 2020. The project has been presented at the 2018 international CTBUH conference in Dubai, the 2019 international CTBUH conference in Chicago, the 2019 Internatio ...

Wooden Architecture
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production of pu ...
