Abstract
WDKM is designed for use in relation to the analysis of large regular structures. The programs of WDKM are capable of calculating any space bar structure of practically arbitrary global geometry and any type of loading. The system requires less data to be fed in than similar ones based on the finite element method. WDKM is based on the theory of difference-matrix description and the numerical algorithm is suitably prepared. Both static and dynamic analyses are possible. In addition, stability problems and frequency of natural vibrations can be analysed. Large displacements of nodes can be taken into consideration. Moreover, large longitudinal and shear forces in bars are taken into account. Effective computer-aided dimensioning of regular structures is also incorporated in the system.
