Which load is categorized as a dead load?

1. The unexpected weight from wind

2. The weight of the structure itself

3. The weight added during construction

4. The shifting of soil over time

The correct answer is: The weight of the structure itself

The weight of the structure itself is classified as a dead load because it represents a permanent, static load that remains constant throughout the life of the structure. Dead loads include all the materials that make up the construction, such as beams, walls, roofs, and any permanent fixtures. These loads are crucial in design calculations since they influence the structural integrity and stability of the building or bridge. In contrast, the unexpected weight from wind is categorized as a live load or lateral load, as it is variable and dynamic, depending on environmental conditions. The weight added during construction may temporarily increase the load but does not constitute a dead load once the structure is completed. Shifting soil over time could induce changes in load but like wind, it does not classify as a dead load due to its variable nature.
