The correct term for the weight of all building materials and parts that are permanently attached to a structure is referred to as the dead load. Dead loads consist of the weight of the structural components such as walls, floors, roofs, and any fixed installations within the building. This weight is static and does not change over time, which distinguishes it from other types of loads that may be dynamic or variable.

Understanding dead loads is crucial in the field of structural engineering and safety, as they are a primary consideration in the design and analysis of a building. Engineers must ensure that the structure is capable of supporting these loads safely throughout its lifespan.

In contrast, other load types, like impact loads, involve forces that develop from dynamic actions, such as moving vehicles or people. Compression loads refer to forces that tend to shorten or squeeze materials, while shear loads are related to forces that can cause layers of material to slide past one another. Each of these loads plays a significant role in structural integrity, but they do not represent the static weight of the building itself.
