Steel structures with partially restrained columns

Inside this paper, the test results from a set of three dimensional subassemblage tests which were conducted in the University of Sheffield in U.K. are discussed. A brief introduction of the development of a three dimensional subassemblage computer program developed in the University of Sheffield is included. The validity of this computer program is established by comparison of the predicted results with actual test records for the subassemblage tests. It is evident that the analytical model closely simulates all aspects of the observed experimental behaviour. The reliability of the program is thus established.
