/lɒŋɡɪˈtjuːdɪnəl prɛsˈtrɛsɪŋ/

Meaning and Usage

Longitudinal prestressing refers to the process employed in civil engineering and structural design where tendons or cables are tensioned along the length of a structural element, such as a beam or slab, before the concrete is cast. This technique is used to enhance the tensile strength of concrete structures, reducing cracking and improving overall load-bearing capacity.

This term is relatively specialized and more common in technical and engineering contexts than in general conversation. It is primarily used in written contexts, such as academic papers, engineering documents, and textbooks.

Example Sentences

1. The engineer decided to use longitudinal prestressing in the bridge design to improve its durability.

2. Инженер решил использовать продольное предварительное напряжение в проекте моста для повышения его прочности.

3. Longitudinal prestressing can significantly decrease the amount of deflection in large concrete slabs.

4. Продольное предварительное напряжение может значительно снизить величину прогиба в больших бетонных плитах.

5. Many modern structures rely on longitudinal prestressing techniques for their stability under heavy loads.

6. Многие современные конструкции полагаются на техники продольного предварительного напряжения для своей устойчивости под тяжелыми нагрузками.

Idiomatic Expressions

Although "longitudinal prestressing" does not have commonly recognized idiomatic expressions associated with it, the concept of prestressing in engineering has some phrases related to tension and force in engineering discourse.

1. "Tension under control" - Using longitudinal prestressing effectively keeps the forces within a structure manageable.

2. Контроль за напряжением - использование продольного предварительного напряжения эффективно удерживает силы внутри конструкции в управляемом состоянии.

3. "Pulling in opposite directions" - In bridge designs, longitudinal prestressing accomplishes the task of pulling from both ends to balance forces.

4. Тянуть в противоположные стороны - в проектировании мостов продольное предварительное напряжение выполняет задачу натяжения с обоих концов для балансировки сил.

5. "Bending the rules" - Engineers often explore innovative ways of using longitudinal prestressing to enhance designs beyond conventional methods.

6. Изгибать правила - инженеры часто исследуют инновационные способы использования продольного предварительного напряжения для повышения эффективности проектирования за пределами традиционных методов.

Etymology

The term longitudinal comes from the Latin word longitudinalis, which means "lengthwise," derived from longitudo, meaning "length." Prestressing combines "pre-" meaning "before" and "stress," from Latin stringere, which means "to draw tight." Together, they describe a method where stress is applied before the structure is subjected to loading.
