Vertical load is the downward force applied to a structure from weight such as building materials, occupants, and equipment.

Vertical load refers to the downward forces acting on a building or structural element due to gravity. These loads include the weight of the structure itself, known as dead load, as well as additional imposed loads such as occupants, furniture, equipment, and stored materials, commonly referred to as live loads.

In construction and structural engineering, vertical loads are transferred through beams, columns, load-bearing walls, and foundations to the ground. Proper load paths are critical to ensure forces are distributed safely without overstressing individual components. Vertical load calculations influence member sizing, foundation design, and overall structural stability.

From a code and safety standpoint, vertical loads are defined and regulated by building codes and structural standards. Designers must account for maximum anticipated loads, safety factors, and material properties. Accurately designing for vertical loads ensures buildings can safely support everyday use and long-term service conditions.

Every structural element in a building—from the roof down to the footing—plays a role in safely carrying vertical loads to the ground.
