What Is Cable In Civil Engineering
A cable is a linear element that cannot bear bending or compression due to its small cross-sectional dimensions relative to its length.
What are the different types of cable structures?
Cable structures are commonly used in bridge engineering, offering an elegant and cost-effective alternative. The main types of cable structures used are stayed cables for cable-stayed bridges, main cables and suspenders for suspension bridges, and hangers for arch bridges.
What are the uses of cables?
Cables are used to transmit large tensile forces and are commonly used in lifting and pulling heavy objects, raising elevators, guying towers, and supporting suspension bridges. They cannot resist compression and have little resistance to bending, but can be curved as well as straight.
Are steel cables effective members of the roof structure?
Yes, in tension structures, steel cables are effective members of the roof structure and not just conveyors of forces from the structure to the anchorages.
A cable is a structural member that is linear in shape and cannot withstand bending or compression due to its small cross-sectional dimension relative to its length.
What is the difference between a cable and a member?
Cables are a type of member that can only be analyzed through Non-Linear Analysis as they are tension-only and exhibit non-linear behavior with large displacements. Cables do not have any flexural, torsional, or shear capacity and are never in compression. Members, on the other hand, can have multiple types of loading or behavior.
How to solve cable structures under different load conditions?
A general procedure for solving cable structures under different load conditions has been developed. This procedure utilizes the three dimensional vector form solution of the cable structure, allowing for the derivation of compatibility conditions in the global reference system. Using this method, accurate solutions for cable structures under various load conditions can be obtained.
What is the distinguishing feature of a cable?
A cable's distinguishing feature is its ability to take different shapes based on the type of load applied to it. Under a uniform load, it adopts a curved shape, while a concentrated load causes it to form several linear segments.
Cables are categorized into 5 types based on their purpose: ribbon electric cables for transmitting multiple data simultaneously, shielded cables, twisted pair cables, coaxial cables, and fibre optics cable. These cables are used for various interconnection needs, including connecting the CPU with the motherboard and networking devices.
What are the different types of cables?
There are two types of cable structures: suspension type cables and stayed type cables. The suspension type cables are used in iconic structures such as the Golden Gate Bridge and the Akashi Kaikyo Suspension Bridge. The load bearing mechanism of a suspension bridge involves the cables carrying the weight of the bridge deck.
What is a cable structure?
A cable structure is a type of long-span structure that relies on suspension cables for support under tension. It includes various architectural forms such as suspension bridges, cable-stayed roofs, and bicycle-wheel roofs. Cable structures are highly efficient.
What is the difference between cable and construction?
Cable is a collection of twisted ropes or wires used for strength, while construction refers to the techniques and industry involved in the building of structures.
What is a cable used for?
Cables are utilized in various engineering applications to support transverse loads by utilizing tensile resistance and are commonly found in suspension bridges, transmission lines, and offshore platforms.
Electrical cables facilitate the transfer of electrical signals or power between multiple devices. Undersea cables facilitate long-distance communication. High-voltage cables are used for the bulk transmission of alternating and direct current power.
What are electrical cables used for?
Electrical cables are commonly used for building wiring, providing a permanent installation for lighting, power and control circuits. It saves on installation labor by allowing all necessary conductors to be installed at once.
What is the construction of cable?
The construction of an electrical power cable involves the joining of two or more electrical conductors with an outer sheath, which is used for the transmission and distribution of electrical energy.
A cable roof structure is a type of load-bearing roofing system that employs steel cables. It can be classified into two types: cable-suspended, which directly bears the weight of the roof, and cable-supported.
Are high-strength steel cables efficient for long-span roof construction?
High-strength steel cables are efficient for long-span roof construction as they resist loads solely by axial tension and are relatively low cost for the load-carrying capacity provided.
What are the advantages of high-strength steel cables?
High-strength steel cables are efficient for long-span roof construction as they resist loads solely by axial tension. They provide a cost-effective load-carrying capacity compared to other systems.
Why do steel cables remain in tension under wind uplift?
Steel cables in roof structures are expected to remain in tension even under wind uplift due to the dead weight of the roof. In some roof structures, the steel cables are effective members of the roof structure and not just conveyors of forces from the structure to the anchorages.
