Experimental and theoretical observations allowed us to present some new conclusions concerning the proper, and safe designing of the structures composed of thin-walled bars (TWB). These structures are very sensitive to small changes of cross-sections (CS) - their dimensions, boundary conditions (BC), material properties etc.. Almost all contemporary structures may be considered (as comprising the elements) of a such type. It makes the effects of this work so important. Below we quoted only some most significant conclusions.
