Structural load refers to the weight and forces that a building or structure must support. This includes the weight of the materials used in construction, such as concrete, steel, and wood, as well as any additional loads from occupants, furniture, and equipment. Understanding these loads is crucial for ensuring the safety and stability of a structure. There are different types of structural loads, including dead loads, which are permanent and static, and live loads, which are temporary and dynamic. Engineers must calculate these loads to design structures that can withstand various conditions, such as wind, earthquakes, and snow. Proper load management helps prevent structural failure and ensures longevity.
