Abstract

Abstract

The structure of stainless steel sandwich panel is a new type of prefabricated structural system. In order to reveal the compression properties of core tubes for the structure of stainless steel sandwich panel, a total of 12 sets of specimens which included 212 components were manufactured, and the compression strengths and compression moduli of the core tubes for the structure of stainless steel sandwich panel were obtained. Then the finite element analysis was used to simulate the test process, and the comparison of finite element calculation results the experimental results were in good agreement, which could verify the accuracy of the finite element method. And the theoretical analysis of the compression properties for core tubes was carried out. The research showed that the stress process of core tubes for the structure of stainless steel sandwich panel could be divided into three stages:elastic stage, elastic-plastic stage and failure stage, and it was found that the essence of core tube damage was the local buckling failure at the end of the core tube. Finally, the theoretical calculation formula for the compression strength design value of core tubes for the structure of stainless steel sandwich panel was given.
