What is an impact load?

An impact load refers to a load that is applied suddenly, typically due to an object in motion striking another object or surface. This type of load can create a significant force over a short duration, which may lead to dynamic responses in structures, such as vibrations or even failure if the structure is not designed to withstand such forces.

Impact loads are critical to consider in building construction, particularly in areas where heavy machinery or vehicles operate, as well as in the design of bridges where moving traffic can exert these types of forces. The characteristics of impact loads differ from static loads, where the force is applied gradually or remains constant over time. Understanding the nature of impact loads is essential for engineers to ensure structural integrity and safety under various conditions.
