−	Loads ~~generally~~ are forces that may cause stresses, deformations, displacement and accelerations on a building. Different types of load can act upon a structure or building element, the nature of which will vary according to design, location, and so on. Assessing ~~live and dead~~ loads forms part of an engineer’s structural calculations – a crucial part of ensuring the safe design of building structures and other built assets such as tunnels, bridges and dams.	+	Loads are forces that may cause stresses, deformations, displacement and accelerations on a building.

−	Dead loads can be calculated by assessing the weights of materials specified and their volume as shown on drawings. This means that in theory, it should be possible to calculate dead loads with a good degree of accuracy. However, structural engineers are sometimes conservative with their estimates, minimising acceptable deflections, allowing a margin of error and allowing for alterations over time, and so design dead loads often far exceed those experienced in practice.	+	For more information see: Dead loads.
