The collapse of rigidly jointed singly redundant light alloy trusses

The behaviour of rigidly-jointed redundant trusses when loaded to collapse is investigated both theoretically and experimentally. Trusses which apart from the effect of joint rigidity are singly redundant are considered, and it is shown that their behaviour can be predicted by a method due to Ziegler if the relationships between axial load and axial deformation are known. For a particular set of model light alloy trusses the behaviour under steadily increasing load is predicted using axial load-axial deformation relations for the compression members obtained in a previous series of tests. Satisfactory agreement between predicted and observed collapse loads is demonstrated and the ability of the trusses to carry additional load after buckling of the compression members is also shown.
