TENSION MEMBER Meaning and
Definition
-
A tension member is a structural component that is primarily subjected to tensile forces or stresses. It is specifically designed and employed in engineering and construction projects to resist pulling or stretching forces acting on a structure or system.
In practice, tension members are commonly used in the construction of bridges, buildings, and other structures where load-bearing capacity and structural integrity are essential. They are typically fabricated from materials known for their high tensile strength, such as steel, cables, ropes, or wires.
The primary function of a tension member is to bear and transmit tensile loads or forces in a structural system. These forces include direct tensile loads, as well as loads resulting from wind, seismic activity, dynamic forces, or other external factors.
Tension members are subjected to minimal compressive forces compared to other structural components like compression members or beams. Their ability to resist tensile forces is crucial for maintaining the stability and safety of the overall structure.
The design and size of a tension member depend on factors such as the magnitude and nature of the forces, working conditions, available materials, and desired safety factors. Detailed calculations regarding the allowable stress and deformation are performed to ensure the appropriate selection and configuration of the tension member.
Overall, tension members play a vital role in ensuring the structural integrity and load-bearing capacity of various constructions, providing the necessary support to withstand and distribute tensile loads efficiently.
Etymology of TENSION MEMBER
The etymology of the word "tension member" can be broken down as follows:
1. Tension: The word "tension" originates from the Latin word "tensio", which means "a stretching" or "a straining". It has the same root as the word "tense". In the context of engineering and structures, tension refers to a stretching force that is exerted on a material, typically as a result of pulling or stretching.
2. Member: The word "member" comes from the Latin word "membra", which means "a part" or "a limb". In engineering, a member refers to a structural component of a system or a structure that carries loads and provides support.
Therefore, when combined, "tension member" refers to a structural component that is subjected to tensile forces or stretches under loading conditions.
