摘要: 基于已有的试验研究与理论分析,给出了矩形钢管混凝土中钢管不出现局部屈曲时的最大宽厚比限值,同时提出大宽厚比下矩形钢管混凝土中考虑钢管屈曲的承载力计算方法。通过回归分析给出了矩形钢管混凝土轴压短柱、轴压中长柱的承载力简化计算公式,简化计算结果和大量试验结果进行对比,用试验结果验证了简化计算结果的正确性。同时,采用CECS、DBJ、EC4、LFRD及AIJ规程计算了矩形钢管混凝土承载力并和试验结果进行对比,对比结果表明:欧洲EC4规程、DBJ规程及简化计算结果与试验结果较为接近,所提出的简化计算公式不仅适用于普通宽厚比下矩形钢管混凝土承载力计算,且适用于大宽厚比下考虑局部屈曲时承载力计算,实现了普通壁厚和薄壁矩形钢管混凝土承载力计算公式的统一。Abstract: In this paper,the maximum depth-to-thickness ratio of steel plate without local buckling is given,and an equation for the calculation of bearing capacity of composite sections with both stocky and slender steel elements has been proposed and validated against extensive experimental results available in the literatures.At the same time,the experimental results are compared with the results calculated according to CECS code,DBJ code,EC4 code,LFRD code and AIJ code,and among them the simplified method in this paper is best to calculate the bearing capacity of specimen.The simplified method can be used to calculate the bearing capacity of rectangular composite columns with thick or slender steel plate.
