摘要

摘要: 通过对收集到的现有圆形不锈钢管混凝土试验数据与现行普通钢管混凝土设计标准推荐算式轴压承载力计算结果进行比较，表明现行标准的计算结果偏于保守，有必要提出针对不锈钢管混凝土的承载力简化计算式。鉴于此，建立了圆形不锈钢管混凝土轴压构件的有限元模型，并利用数值模型对影响圆形不锈钢管混凝土轴压承载力的因素进行分析。结果表明：其轴压强度承载力随着不锈钢屈服强度、混凝土强度和含钢率的增加而提高。在参数分析结果的基础上，回归了圆形不锈钢管混凝土轴压强度承载力的简化计算式，并进一步得出轴压稳定承载力的简化计算式。提出的简化式对试验数据的计算结果较现行标准推荐方法更合理。

Abstract: The experimental data of circular concrete filled stainless steel tube (CFSST) were collected and compared with the calculation values of current normal concrete filled steel tube codes. The results showed that the calculation values of current codes were more conservative. Therefore, it is necessary to provide a simplified calculation formula for the bearing capacity of CFSST. In view of this, the finite element (FE) model of CFSST member was established, and the parameters affecting the axial compression bearing capacity of CFSST were analyzed by using the FE model. The results showed that the axial compression strength bearing capacity increased with the increase of stainless steel yield strength, concrete strength and steel ratio. Based on the regression of the simplified calculation formula of the strength capacity of CFSST under axial compression, the simplified calculation formula of the stability bearing capacity of CFSST under axial compression was obtained. The simplified formula proposed in this paper was more consistent with the test data than the current codes.
