Phonetic Transcription

/ˌʌnˈbɒndɪd ˌpoʊst ˈtɛnʃənɪŋ/

Meaning and Usage

Unbonded post-tensioning refers to a construction technique used primarily in reinforced concrete where steel tendons are placed inside ducts or sleeves that are not bonded to the surrounding concrete. This method allows for individual tensioning of the tendons, providing benefits such as reduced cracking, increased load capacity, and greater spans. This term is primarily used within the contexts of civil engineering and construction. It is more frequently encountered in written texts such as engineering manuals, academic papers, and technical specifications, rather than in oral speech.

Example Sentences

1. The architect chose unbonded post-tensioning to allow for greater flexibility in the design of the structure.

2. Архитектор выбрал не связанную преднапряженность, чтобы обеспечить большую гибкость в проектировании конструкции.

3. Unbonded post-tensioning systems are often favored in high-rise buildings due to their structural efficiency.

4. Не связанные преднапряженные системы часто предпочитаются в высотных зданиях из-за их структурной эффективности.

5. The engineers faced challenges while implementing unbonded post-tensioning in a coastal environment due to corrosion risks.

6. Инженеры столкнулись с проблемами при внедрении не связанной преднапряженности в прибрежной среде из-за риска коррозии.

Idiomatic Expressions

The term “unbonded post-tensioning” is quite technical and not typically featured in idiomatic expressions. Hence, it doesn't have common idioms associated with it, but it can be used in various contexts related to construction and engineering concepts.

However, here are some idiomatic expressions derived from the concept of tensioning or construction, displayed alongside their usage:

1. "Under tension": The team was under tension while completing the project's deadline.

2. Команда была под напряжением, завершая проект в срок.

3. "Tie up loose ends": Before we start the new project, let’s tie up loose ends on the unbonded post-tensioning tasks.

4. Прежде чем мы начнем новый проект, давайте завершим оставшиеся дела по задачам с не связанной преднапряженностью.

5. "Under pressure": The engineers worked under pressure to finish the unbonded post-tensioning installation.

6. Инженеры работали под давлением, чтобы завершить установку не связанной преднапряженности.

Etymology

The term "unbonded post-tensioning" is derived from various roots: - "Unbonded" indicates a lack of adhesive or bonding, originating from the prefix "un-" (not) and "bond" (to join). - "Post-tensioning" consists of "post-", meaning after, and "tensioning" from "tension," which indicates the act of applying force or stress.

The concept itself emerged in civil engineering practices to enhance the performance of concrete constructions in the mid-20th century.
