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 highest, over all, skyscraper. The skyscraper is set to be a mixed-used building including residential, office and retail space. Description It is supposed to be made of 90% wood and the rest being steel, steel braces will be used to enhance resistance to wind and earthquakes due to the area's high seismic activity. Wood was chosen since 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 its aesthetics, is part of a larger movement aiming to "change cities into forests". Wooden structures are also easier to rebuild or replace than concrete ...

Skyscraper
A skyscraper is a tall continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least or in height, though there is no universally accepted definition. Skyscrapers are very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. 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 of those made of reinforced concrete. Modern skyscrapers' walls are not load-bearing, and most skyscrapers are characterised by large surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose 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 it is defined 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 support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between 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, or woodchips or fiber. 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 productio ...

List Of Tallest Buildings In The World
This list of tallest buildings includes skyscrapers with continuously occupiable floors and a height of at least . Non-building structures, such as towers, are not included in this list (for these, see ''List of tallest buildings and structures''). History Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3800 years until the construction of Lincoln Cathedral in 1311. The Strasbourg Cathedral in France, completed in 1439, was the world's tallest building until 1874. The first skyscraper was pioneered in Chicago with the Home Insurance Building in 1885. The United States would hold the position of the world's tallest building throughout the 20th century until 1998, when the Petronas Towers were completed. Since then, two other buildings have gained the title: Taipei 101 in 2004 and Burj Khalifa in 2010. Since the beginning of the 21st century, the Middle East, China, and Southeast Asia have experie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brock Commons Tallwood House
Brock Commons Tallwood House is an 18-storey student residence at the Point Grey Campus of the University of British Columbia (UBC) in Canada. At the time it was opened, it was the tallest mass timber structure in the world. It is the first phase of a complex at Brock Commons. The Brock Hall Annex located at the site will be demolished to make way for a building in phase 2. The 1958 mosaic mural "Symbols of Education" by Lionel and Patricia Thomas, commissioned by the university's 1958 graduating class, will be moved as a result. Construction It was built via the Tall Wood Building Demonstration Initiative (TWBDI) of Natural Resources Canada that in October 2017 led to the establishment of the Green Construction Through Wood (GCWood) program. Acton Ostry Architects designed the building with structural engineering firm Fast + Epp, which received consultation services from Architekten Hermann Kaufmann of Vorarlberg, Austria, for tall-wood construction.

Architectural Firm
In the United States, an architectural firm or architecture firm is a business that employs one or more licensed architects and practices the profession of architecture; while in South Africa, the United Kingdom, Ireland, Denmark and other countries, an architectural firm is a company that offers architectural services. History Architects (or master builders) have existed since early in recorded history. The earliest recorded architects include Imhotep (c. 2600 BCE) and Senemut (c. 1470 BCE). No writings exist to describe how these architects performed their work. However, as nobles it is reasonable to assume they had staffs of assistants and retainers to help refine and implement their work. The oldest surviving book on architecture, ''De architectura'' by the Roman architect Vitruvius describes the design and construction of towns, buildings, clocks, and machines, but provides no information about the organisation of the architect's assistants. It is generally accepted that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismic Wave
A seismic wave is a wave of acoustic energy that travels through the Earth. It can result from an earthquake, volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy. Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones (in water), or accelerometers. Seismic waves are distinguished from seismic noise (ambient vibration), which is persistent low-amplitude vibration arising from a variety of natural and anthropogenic sources. The propagation velocity of a seismic wave depends on density and elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust and mantle, but drops sharply going from the mantle to Earth's outer core. Earthquakes create distinct types of waves with different velocities. When recorded by a seismic observatory, their different travel times help scientists locate the quake's hypocen ...

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have various asp ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Wooden Buildings
Wooden buildings which have exceptional heights are in this article listed, starting with the highest wooden structures. The tallest ever wooden structure was the tower of Mühlacker radio transmitter (, destroyed in 1945). The tallest standing wooden structure is Gliwice Radio Tower (). In a narrower sense these structures are not buildings. The tallest building has been the Sanctuary of Truth, a temple in Pattaya, Thailand. The previous record holder, the Pagoda of Fogong Temple, was built 900 years ago.

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 o ...
