What are loads in the context of structural engineering?

In structural engineering, loads refer specifically to the forces that a structure must support or withstand during its lifespan. This includes not only the weight of the building itself and the materials used but also the effects of various environmental factors such as wind, snow, and seismic activity. Understanding these loads is crucial for engineers as they determine how to design and construct structures that are safe and stable.

The forces resulting from building materials and environmental effects encompass both static loads, like the dead weight of the structure, and dynamic loads, such as those imposed by moving vehicles or people. Engineers analyze these loads to ensure that each component of the structure can handle the expected stresses and strains, thus ensuring safety and durability over time. This understanding allows for effective design choices that appropriately account for weight distribution, material selection, and structural integrity.
