摘要
文中对6个自然锈蚀的钢管混凝土进行抗压试验,分析锈蚀对试件力学性能的影响。基于三维扫描技术和分形理论分析,提出计算锈蚀钢管表面分形维数指标的方法,并分析得出分形维数与试件抗压承载力的关系。
Six naturally corroded concrete-filled steel tube compressive tests were carried out to analyze the influence of corrosion on the mechanical properties of specimens.Based on the analysis of three-dimensional scanning technology and fractal theory,a method for calculating the fractal dimension index of the corroded steel pipe surface is proposed,and the relationship between the fractal dimension and the compressive bearing capacity of the specimen is analyzed.
