A nonbuilding structure, often referred to simply as a structure, is any built structure or construction structure that is not a building, i.e. not designed for continuous human occupancy. The term is particularly used by architects, structural engineers, and mechanical engineers to distinguish load-bearing structures not designed for continuous human occupancy.
A bird strike (sometimes called birdstrike, bird ingestion (for an engine), bird hit, or bird aircraft strike hazard (BASH)) is a collision between a flying animal (usually a bird, occasionally bat) and a moving vehicle (typically an aircraft, occasionally high-speed train or automobile). The term is also used for bird deaths resulting from collisions with highrise buildings, towers (see bird–skyscraper collisions and towerkill) and tall structures such as overhead power lines and wind turbines.
A significant threat to aviation safety, bird strikes have caused a number of accidents with human casualties. There are over 13,000 bird strikes annually in the US alone. However, the number of major accidents involving civil aircraft is quite low and it has been estimated that there is only about one accident resulting in human death in one billion (10) flying hours. The majority of bird strikes (65%) cause little damage to the aircraft; however, the collision is usually fatal to the bird(s) involved.
This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least 350 metres (1,150 ft). Such definition excludes non-building structures, such as towers.
A building code (also building control or building regulations) is a set of rules that specify the standards for construction objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission, usually from a local council. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures — for example, the building codes in many countries require engineers to consider the effects of soil liquefaction in the design of new buildings. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority.
Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants, and others. Codes regulate the design and construction of structures where adopted into law.
A power cable is an electrical cable used specifically for transmission of electrical power. It is an assembly of one or more electrical conductors, usually held together in a single bundle with an insulating sheath, although some power cables are simply rigged as exposed live wires. Power cables may be detachable portable cords (typically coupled with adaptors), or installed as permanent wirings within buildings and structures, buried in the ground, laid underwater or run overhead. Power cables that are bundled inside thermoplastic sheathing and that are intended to be run inside a building are known as NM-B (nonmetallic sheathed building cable).
Small flexible power cables are used for electrical devices such as computers and peripherals, mobile devices, home appliances, light fixtures, power tools and machinery, as well as household lighting, heating, air conditioning and rooftop photovoltaic and home energy storage systems. Larger power cables are used for transmission of grid electricity to supply industrial, commercial and residential demands, as well as a significant portion of mass transit and freight transport (particularly rail transport).
A synanthrope (from Ancient Greek σύν (sýn) 'together, with' and ἄνθρωπος (ánthrōpos) 'man') is an organism that evolved to live near humans and benefit from human settlements and their environmental modifications (see also anthropophilia for animals who live close to humans as parasites). The term includes many animals and plants regarded as pests or weeds, but does not include domesticated species. Common synanthrope habitats include houses, sheds and barns, non-building structures, gardens, parks, farms, road verges and rubbish dumps.
