Which type of loading is specifically considered in structural design?

In structural design, both live and dead loads are critical considerations. Dead loads refer to the permanent static forces acting on a structure, such as the weight of the building materials, fixtures, and other components that remain constant over time. Examples include the weight of beams, columns, floors, and roofs.

Live loads, on the other hand, are dynamic, variable forces that can change throughout the structure's lifetime. These include occupancy loads (people, furniture, and movable items), snow, wind, and other environmental factors that exert force on the structure intermittently.

Both types of loads must be accounted for to ensure the safety, stability, and performance of the structure under various conditions. Engineers analyze these loads during the design process to determine the necessary strength and materials needed to support the structure effectively. This holistic approach helps to safeguard against structural failure and is a standard practice in engineering disciplines.
