Classical methods of Structural Analysis play an important role in understanding the behavior of structures because during the process of solution the conditions of equilibrium and compatibility are used explicitly. Computationally these methods are problem dependent and thus are not suitable for algorithmic programming. Logic programming can be used to implement Classical methods of Structural Analysis. This can formulate the problem on a modern base from which design considerations can be tackled by using Artificial Intelligence methods and Expert Systems. It is anticipated that classical methods as more physical and conceptually clear will provide the required information in a more flexible way that will suit better the problem at hand, avoiding the complete solution or reanalysis of the structure. In this paper three-hinge arch and asteroid trusses are analyzed using logic programming. These topologies are also important for the analysis of statically indeterminate trusses.
