What is cable-stayed roof?
Cable-stayed roof construction is another structural system derived from bridge building. A flat roof structure in bending is supported from above by steel cables radiating downward from masts that rise above roof level; spans of up to 72 metres (236 feet) have been built.
What is cable suspended structure?
A suspended structure is a structure which is supported by cables coming from beams or trusses which sit atop a concrete center column or core. The design allows the walls, roof and cantilevered floors to be supported entirely by cables and a center column.
Where are cable structures used in architecture?
Highly efficient, cable structures include the suspension bridge, the cable-stayed roof, and the bicycle-wheel roof. The graceful curve of the huge main cables of a suspension bridge is almost a catenary, the shape assumed by any string or cable suspended freely between two points.
What is the meaning of monitor roof?
A monitor in architecture is a raised structure running along the ridge of a double-pitched roof, with its own roof running parallel with the main roof. The long sides of monitors usually contain clerestory windows or louvers to light or ventilate the area under the roof.
What is cable supported structure?
Cable-supporting structures are additional hardware for supporting communication cables. These are usually in addition to the cable pathways that are usually installed when a building is constructed. Cable-supporting structures are often required to augment existing cable pathways because they become full of cables.
What are the advantages and disadvantages of cable-stayed bridges?
Although a cable-stayed bridge can help to provide a consistently supportive deck when there are crosswinds present over a span, this option does not work well when the speed of that wind remains consistently high. This disadvantage occurs because of the rigidity that the cables provide for the overall structure.
How is a cable-stayed bridge constructed?
Construction of cable-stayed bridges usually follows the cantilever method, so their construction begins with the sinking of caissons and the erection of towers and anchorages. After the tower is built, one cable and a section of the deck are constructed in each direction.
What is monitor roof truss?
Tubular Monitor Roof Truss This is a flat roof with raised portions called monitors, used to admit light.
What is half monitor roof?
Definition of half-monitor : a roof for hog or poultry houses shaped like a saw tooth.
What is a disadvantages of cable stay?
What is 1 advantage to a cable-stayed bridge?
The following are key advantages of the cable-stayed form: much greater stiffness than the suspension bridge, so that deformations of the deck under live loads are reduced. can be constructed by cantilevering out from the tower – the cables act both as temporary and permanent supports to the bridge deck.
What materials are used to build cable-stayed bridges?
The primary construction materials used in cable-stayed bridges are:
- For decks: reinforced or prestressed concrete, composite concrete-steel, or orthotropic steel decks;
- For deck-girders: beams of prestressed concrete or steel, box girders of prestressed concrete or steel, similar to those in modern suspension bridges;
What materials are cable-stayed bridges made of?
What is the average span of a cable-stayed bridge?
110 to 480 meters
The typical span length of cable stayed bridges range from 110 to 480 meters. The longest cable stayed bridge in the world is presently the Tatara Bridge with a main span of 890 m. The articulation of the structure allows for a shallow superstructure with open and uncluttered views from the bridge.
Why is it called a monitor roof?
What is the length of the cables of the stadium roof?
The front and back stay cables are suspended by four 63 m high masts located at the corners of the stadium (Kim 2001). The roof of Braga Municipal Sports Stadium, Portugal, constructed in 2001, is formed by pairs of full locked coil cables spanning 202m and supporting two concrete slabs of thickness 0.25 m and length 57.3m.
What is the cable-stayed roof of conference center?
The studied application is the cable-stayed roof of the Conference Center located in Smart Village, Giza, Egypt, constructed in 2002 (Smart Villages 2015). The main structural system of conference center is a space truss roof supported by cables connected to six masts, as shown in Fig. 8.
What are the advantages of cables roof structures?
Introduction Cables structures have been used as wide span roof structures due to their various advantages such as high strength, light weight, design flexibility, cost-effective construction and innovative forms.
Can We model the cable-stayed roof of a wide span Hall?
Conclusions This paper presented finite element modeling and nonlinear analysis for the cable-stayed roofs of wide span halls. Formulation of the cable element is given together with the nonlinear analysis parameters and adopted optimization procedure.
