Abstract:

The report presents the results of a survey of the literature dealing with the analysis and design of grillages under normal and axial loads. The requirements of a rigorous design procedure are outlined and compared with the strongly empirical approaches currently employed. The following methods of analysis applicable to grillage structures are discussed the differential and integral equation and energy formulation in terms of plate and beam theories, the analysis of an equivalent orthotropic plate or beam grid, and the discrete element methods. The survey has shown that neither a completely satisfactory method for the working stress analysis nor a method for the ultimate strength analysis of grillages under combined normal and axial loads is yet available. It is suggested that one of the discrete element methods, either the lumped parameter or finite element approach, be adapted for both the working stress and ultimate strength analysis of grillages under combined loads.
