Abstract: In a paper are determinated an area of using composite tubes as structures. Considered four existing analytical methods for determination a load capacity of composite tubes with circular cross-section under axial compression are using in Ukraine and abroad. Analyzed approaches to the questions of a limit compression load (load capacity) calculation are able to withstand a composite element. Highlighted the fundamental features and similarities of discussed methods, and also their shortcomings affecting to the accuracy of the strength and stability computing results for composite tubes. On the particular example performed a results comparison of determining the load capacity by the four methods and determinated a difference which is varies (in relative units) within 1,08…1.38.

Keywords: composite tubes, analytical methods of calculation, joint work, axial compression, load capacity, strength and stability of structures, reduced flexibility, contact between materials.
