What term describes the combined weight of all formwork and concrete?

The term that describes the combined weight of all formwork and concrete is "Dead Load." Dead loads are permanent static forces that are essentially constant and act on a structure over time. They include the weight of structural elements like beams, slabs, and any additional materials permanently attached to the building, such as formwork and concrete.

Understanding dead loads is crucial for structural design, as engineers must assess these weights during the planning phase to ensure that a structure can safely support both its own weight and any additional loads that may be imposed on it over time. By defining dead loads clearly, builders can better estimate the necessary strength and stability required in their structures to withstand these permanent forces.

Live loads, in contrast to dead loads, refer to variable forces that change over time, such as people, furniture, and vehicles. Static loads are forces that do not change position or magnitude, while dynamic loads encompass forces that can vary or change, such as wind, seismic activity, or moving vehicles. Thus, identifying the weight of the concrete and formwork specifically falls under the category of dead load.
