The Institution came into being on 21 July 1908 as the Concrete Institute, as the result of a much-felt need to define rules for the proper use of concrete in buildings. Incorporated, in 1909, as a company limited by guarantee, it was renamed the Institution of Structural Engineers in 1922, when its areas of interest were extended to cover `structures` of all kinds-`structures` being defined as `those constructions which are subject principally to the laws of statics as opposed to those which are subject to the laws of dynamics and kinetics, such as engines and machines`.
