Experimental study of frame-rod structures with elements of thin-walled steel profiles
Discusses the results of experimental rimentale-theoretical research of the building frame based on the tone-kostenich cold-formed profiles. In the course of research, the stress-strain state of the RA-we from thin-walled profiles was studied; the method of preliminary modeling of structural elements using FEM was developed; the design of the test bench and the composition of the test program of frames from thin-boned steel pro-files was developed; the comparison of the results of theoretical and experimental studies; the completion of numerical calculations of the con-struction nodes; the features of work under load and its compliance with the applied design scheme are studied.
