Analytical Methods for Determination a Load Capacity of Concrete-Filled Tubes under Axial Compression

Abstract

In a paper are considered four existing analytical methods for determination a bearing capacity of concrete-filled tubes structures under axial compression. Analyzed approaches to the questions of a limit compression load 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. On the particular example performed a results comparison of determination the bearing capacity by the four methods.
