Construction work is the way in which the building elements and the entire structural system respond to the loads acting on them. Loads result in deformations, displacements and the distribution of internal forces. It involves the interaction of individual load-bearing elements under permanent, variable and exceptional loads.
In engineering practice, this term refers both to the behaviour of the structure as a whole and to the local working of its individual parts. The working of a structure depends on the static scheme adopted, the stiffness of the components, the type of connections and the material properties.
Its nature can change over time, for example as a result of building settlement, temperature changes or prolonged exposure to loads. A correct analysis of the performance of the structure makes it possible to assess the safety, comfort and durability of the building throughout its lifetime.
