Columns of Concrete-Filled Rectangular Hollow Sectionsby H. Shakir-Khalil, Univ of Manchester, Manchester, United Kingdom,
Abstract: Concrete-filled hollow sections are normally used as columns in multi-storey buildings and also in similar structures. Such columns may be filled with plain concrete with no need for any reinforcement. This type of column has been the subject of a great deal of theoretical and experimental investigations, and its design is covered by the British Standard BS5400. The paper gives a summary of the Standard as applied to this particular type of column, and also the results of some recent investigations in the behaviour of concrete-filled rectangular hollow section columns. A comparison between the British Standards BS5400 and BS5950 for the design of composite and steel columns is also included underlining the beneficial effect of using a concrete infill.
