Which load factor is typically applied to live load in buildings?

In building design, live loads refer to the transient forces exerted on a structure by its occupants, furniture, and other movable elements. The use of load factors during the design process is crucial to ensure the safety and stability of a structure under expected conditions.

The correct answer indicates a factor of 1.6, which is commonly applied to live loads in design. This factor accounts for uncertainties in the estimation of live loads, variations in use, and unexpected increases in load due to factors such as occupancy changes and functionality. By using a load factor of 1.6, designers incorporate a safety margin that ensures structures can withstand more than just the calculated live loads, thus enhancing structural integrity under various conditions.

This approach aligns with standard codes and practices in structural engineering, which dictate the necessity of safety factors to address risks associated with dynamic loads. Thus, a factor of 1.6 represents a conservative approach to load calculations that prioritizes safety while accounting for the flexible nature of live loads in buildings.
