Abstract

Abstract

The bamboo winding composite pipe is a new type of environmentally-friendly material independently developed in China. In order to study the reinforced thin-walled circular steel tube composite structures, axial compression tests were conducted on the composite specimens, and the failure modes and bearing capacity of the composite specimens were studied. Trends of load versus displacement and strain were analyzed, and a theoretical calculation formula for the axial compression ultimate bearing capacity of the composite specimens was proposed. Finally, ABAQUS finite element software was used to analyze the parametric analysis of the composite specimen, as well as the influence of the thickness of bamboo winding composite pipe and other parameters on the axial compression performance. The experimental results showed that the failure mode of the composite specimens was lateral bending failure in the middle section of the specimen. Compared to pure bamboo winding composite pipes and steel tubes, the ultimate bearing capacity of the composite specimens had increased by 6.5 times and 1.5 times, respectively. The experimental results were in good agreement with the finite element simulation results, and the error between the theoretical calculation bearing capacity formula and the experimental results was 5.9%.
