Definition: The word 'abutment' is a term in civil engineering used to describe structures that are designed to provide support and stability to a column, beam or other structural element. Here's a more detailed definition: A 'butt' is a flat section or sectional member of a structural element that provides the lateral support required for its own weight. The butt is typically made of concrete or steel, as these materials can withstand loads placed on them without cracking or breaking under stress and temperature changes. The term 'butt' also refers to the column, beam, or other structure which is supported by butts. There are many different types of butt structures used in various applications throughout the world, including: 1. Concrete Butt: This type of butt is typically used for beams or columns that will be subjected to high loads such as those from earthquakes or heavy traffic loads. 2. Steel Butt: Steel butt supports are commonly used in bridges and other buildings due to their structural integrity and ease of fabrication. 3. Composite Butt: Composite butt is made up of a lightweight material (such as steel) that has been reinforced with additional materials like concrete, wood or metal to improve its strength and performance. Each type of butt can have specific requirements and considerations that must be taken into account when designing an abutment system for a structure. These considerations include the required load capacity, strength of the structural element, stability, and safety aspects such as durability and longevity.
