Abstract
The present author was published the series of the papers concerning the foundations of the large program system WDKM. There can be mentioned the proceedings of the int.conferences in Guildford (1984), (& 1985), Beijing (1987), Singapore (1990), in some books, (1980, 1985, 1991, 1997a), and the others. In proposed now paper, are shown some numerical examples of application the simplest composite bars (CB), and influence of it on behaviour of real structure: on stresses distribution, deflections, on possible instability of the bar and whole structure. There are mentioned some simplest programs, which in nearest future will play a part of subroutines for larger program systems as mentioned WDKM, or wider new version called NAAS-CLASS (Obr_bski (1997b)). The mentioned programs enable automatic dimensioning of the structures composed of numerous CB forming large trusses or frames. The works over inclusion of mentioned above separate programs to larger program systems, enlargement of new units but also adaptation of old versions written for old large computers to PC, are continued.
