Escalator
An escalator is a moving staircase which carries people between floors of a building or structure. It consists of a motor-driven chain of individually linked steps on a track which cycle on a pair of tracks which keep the step tread horizontal. Escalators are often used around the world in places where lifts would be impractical, or they can be used in conjunction with them. Principal areas of usage include department stores, shopping malls, airports, transit systems (railway/railroad stations), convention centers, hotels, arenas, stadiums and public buildings. Escalators have the capacity to move large numbers of people. They have no waiting interval (except during very heavy traffic). They can be used to guide people toward main exits or special exhibits and may be weatherproofed for outdoor use. A non-functional escalator can function as a normal staircase, whereas many other methods of transport become useless when they break down or lose power. Design, components, ...

Moving Walkway
A moving walkway, also known as an autowalk, moving pavement, moving sidewalk, people-mover, travolator, or travelator, is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction. History The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois, in the United States as ''The Great Wharf Moving Sidewalk'' and was designed by architect Joseph Lyman Silsbee. It had two different divisions: one where passengers were seated, and one where riders could stand or walk. It ran in a loop down the length of a lakefront pier to a casino. Six years later a moving walkway was also presented to the public at the 1900 Exposition Universelle in Paris as the ''Rue de l'Avenir''. The walkway consisted of three elevated platforms, the first was stationary, the second m ...

Elevator
An elevator or lift is a cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or decks of a building, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are often a legal requirement in new multistory buildings, espec ...

Metro Station
A metro station or subway station is a station for a rapid transit system, which as a whole is usually called a "metro" or "subway". A station provides a means for passengers to purchase tickets, board trains, and evacuate the system in the case of an emergency. In the United Kingdom, they are known as underground stations, most commonly used in reference to the London Underground. Location The location of a metro station is carefully planned to provide easy access to important urban facilities such as roads, commercial centres, major buildings and other transport nodes. Most stations are located underground, with entrances/exits leading up to ground or street level. The bulk of the station is typically positioned under land reserved for public thoroughfares or parks. Placing the station underground reduces the outside area occupied by the station, allowing vehicles and pedestrians to continue using the ground-level area in a similar way as before the station's constru ...

Shopping Mall
A shopping mall (or simply mall) is a North American term for a large indoor shopping center, usually Anchor tenant, anchored by department stores. The term "mall" originally meant pedestrian zone, a pedestrian promenade with shops along it (that is, the term was used to refer to the walkway itself which was merely bordered by such shops), but in the late 1960s, it began to be used as a generic term for the large enclosed shopping centers that were becoming commonplace at the time. In the U.K., such complexes are considered shopping centres (Commonwealth English: shopping centre), though "shopping center" covers many more sizes and types of centers than the North American "mall". Other countries may follow U.S. usage (Philippines, India, United Arab Emirates, U.A.E., etc.) and others (Australia, etc.) follow U.K. usage. In Canadian English, and oftentimes in Australia and New Zealand, 'mall' may be used informally but 'shopping centre' or merely 'centre' will feature in the name of ...

Department Stores
A department store is a retail establishment offering a wide range of consumer goods in different areas of the store, each area ("department") specializing in a product category. In modern major cities, the department store made a dramatic appearance in the middle of the 19th century, and permanently reshaped shopping habits, and the definition of service and luxury. Similar developments were under way in London (with Whiteleys), in Paris ( Le Bon Marché) and in New York ( Stewart's). Today, departments often include the following: clothing, cosmetics, do it yourself, furniture, gardening, hardware, home appliances, houseware, paint, sporting goods, toiletries, and toys. Additionally, other lines of products such as food, books, jewellery, electronics, stationery, photographic equipment, baby products, and products for pets are sometimes included. Customers generally check out near the front of the store in discount department stores, while high-end traditional department stor ...

Shopping Centers
A shopping center (American English) or shopping centre (Commonwealth English), also called a shopping complex, shopping arcade, shopping plaza or galleria, is a group of shops built together, sometimes under one roof. The first known collections of retailers under one roof are public markets, dating back to ancient times, and Middle Eastern covered markets, bazaars and souqs. In Paris, about 150 covered passages were built between the late 18th century and 1850, and a wealth of shopping arcades were built across Europe in the 19th century. In the United States, the widespread use of the automobile in the 1920s led to the first shopping centers of a few dozen shops that included parking for cars. Starting in 1946, larger, open air centers anchored by department stores were built (sometimes as a collection of adjacent retail properties with different owners), then enclosed shopping malls starting with Victor Gruen's Southdale Center near Minneapolis in 1956. A shopping mall ...

Tension Member
Tension members are structural elements that are subjected to axial tensile forces. Examples of tension members are bracing for buildings and bridges, truss members, and cables in suspended roof systems. Calculation In an axially loaded tension member, the stress is given by: F = P/A where P is the magnitude of the load and A is the cross-sectional area. The stress given by this equation is exact, knowing that the cross section is not adjacent to the point of application of the load nor having holes for bolts or other discontinuities. For example, given an 8 x 11.5 plate that is used as a tension member (section a-a) and is connected to a gusset plate with two 7/8-inch-diameter bolts (section b-b): The area at section a - a (gross area of the member) is 8 x ½ = 4 in2 However, the area at section b - b (net area) is (8 – 2 x 7/8) x ½ = 3.12 in2 knowing that the higher stress is located at section b - b due to its smaller area. Design To design tension members, it ...

Movie Theater
A movie theater (American English), cinema (British English), or cinema hall ( Indian English), also known as a movie house, picture house, the movies, the pictures, picture theater, the silver screen, the big screen, or simply theater is a building that contains auditoria for viewing films (also called movies) for entertainment. Most, but not all, movie theaters are commercial operations catering to the general public, who attend by purchasing a ticket. The film is projected with a movie projector onto a large projection screen at the front of the auditorium while the dialogue, sounds, and music are played through a number of wall-mounted speakers. Since the 1970s, subwoofers have been used for low-pitched sounds. Since the 2010s, the majority of movie theaters have been equipped for digital cinema projection, removing the need to create and transport a physical film print on a heavy reel. A great variety of films are shown at cinemas, ranging from animated films to bl ...

Sandwich Panel
A sandwich panel is any structure made of three layers: a low-density core ( PIR, mineral wool, XPS), and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. The structural functionality of a sandwich panel is similar to the classic I-beam, where two face sheets primarily resist the in-plane and lateral bending loads (similar to flanges of an I- beam), while the core material mainly resists the shear loads (similar to the web of an I-beam). The idea is to use a light/soft but thick layer for the core and strong but thin layers for face sheets. This results in increasing the overall thickness of the panel, which often improves the structural attributes, like bending stiffness, and maintain or even reduce the weight. Sandwich panels are an example of a sandwich structured composite: the strength and lightness of this technology makes it popular and widespread. Its versatility ...
