摘要

摘要: 不锈钢芯板结构是一种新型的装配式结构体系。为研究不锈钢芯板结构芯管的平压性能，通过对12组合计212根构件不锈钢芯板结构芯管试件的平压试验，得到了不锈钢芯板结构芯管平压强度和平压模量；然后采用有限元分析来模拟试验过程。有限元计算结果与试验结果的对比表明：两者吻合良好，验证了有限元模型的可靠性；而后对芯管的平压性能进行数值分析。试验和理论结果表明：不锈钢芯板结构芯管在平压作用下的受力过程可以分为三个阶段：弹性阶段、弹塑性阶段和破坏阶段；芯管破坏的本质是芯管端部发生局部屈曲破坏；最后给出了此种不锈钢芯板结构芯管平压强度设计值的理论计算式。

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.
