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 ...

Skyscraper Design And Construction
The design and construction of skyscrapers involves creating safe, habitable spaces in very high buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among the most complex encountered given the balances required between economics, engineering, and construction management. Basic design considerations Good structural design is important in most building designs, but particularly for skyscrapers since even a small chance of catastrophic failure is unacceptable given the high prices of construction and potential risk to human life on a massive scale, as seen in the Surfside condominium collapse of 2021. This presents a paradox to civil engineers: the only way to assure a lack of failure is to test for all modes of failure, in b ...

Mjøstårnet
Mjøstårnet (Norwegian for the tower of Mjøsa) is an 18-storey mixed-use building in Brumunddal, Norway, completed in March 2019. At the time of completion, it was officially the world's tallest wooden building, at tall, before being surpassed by Ascent MKE in August 2022. The building is named after Norway's biggest lake, which is 100 km away from Oslo. Mjøstårnet has a combined floor area of around . The building offers a hotel, apartments, offices, a restaurant and common areas, as well as a swimming pool in the adjacent first-floor extension. This is about in size and also built in wood. Design Mjøstårnet was designed by Norwegian studio Voll Arkitekter for AB Invest. Timber structures were installed by Norwegian firm Moelven Limtre, including load-bearing structures in glued laminated timber. Cross laminated timber were used for stairwells, elevator shafts and balconies. As the main vertical/lateral structural elements and the floor spanning systems of Mjø ...

Skyline
A skyline is the wikt:outline, outline or shape viewed near the horizon. It can be created by a city's overall structure, or by human intervention in a rural area, rural setting, or in nature that is formed where the sky meets buildings or the land. City skylines serve as a pseudo-fingerprint as no two skylines are alike. For this reason, news and sports programs, television shows, and movies often display the skyline of a city to set a location. The term ''The Sky Line of New York City'' was introduced in 1896, when it was the title of a color lithography, lithograph by Charles Graham (artist), Charles Graham for the color supplement of the ''New York Journal-American, New York Journal''. Paul D. Spreiregen, FAIA, has called a [city] skyline "a physical representation [of a city's] facts of life ... a potential work of art ... its collective vista." Features High-rise buildings High-rise buildings, including skyscrapers, are the fundamental feature of urban area, urban skyl ...

List Of Tallest Wooden Buildings
Wooden buildings that have exceptional heights are listed, starting with the tallest wooden structures. Wooden buildings are having a resurgence, as they are considered to be a climate-friendly alternative to some synthetic materials. The tallest recorded wooden structures had been wooden radio masts with heights of up to 220 meters, or 720 feet, constructed in Russia in the first half of the 20th century but they were replaced by steel masts and nuclear power plants. Data verifying the location of these structures is not readily available. The second highest recorded wooden structure was the tower of the Mühlacker radio transmitter (190 meters or 620 feet, destroyed in 1945). The tallest standing wooden structure is the Gliwice Radio Tower (111 m or 364 ft), located in Gliwice, Poland.
