中文摘要：

该文根据收集到的266个方钢管混凝土轴压短柱的试验数据,对美国规范（AISC）、欧洲规范（EC4）、日本规范（AIJ）及中国规范（DL5085、GJB、CECS）进行了承载力比较,比较结果表明AISC、CECS及AIJ偏于保守,EC4稍偏保守的接近于试验结果,而DL5085、GJB稍高于试验结果。同时该文还将现有的五个纤维模型与试验曲线选取特征点进行统计分析,发现纤维模型在弹性阶段跟试验吻合较好,但对下降段及强化段的描述,各已有模型差异较大,有不同的适用范围。

英文摘要：

Based on data from 266 tests of concrete filled steel tubular stub columns gathered trom literature, the design equations for axial load capacities according to domestic and international codes and specifications are examined. It is found that the equations of AISC, CECS and AIJ specifications are most conservative. The EC specifications provide statistically closer but slightly conservative predictions to the test results. The average predictions by DL and GJB specifications are slightly higher than the test data. The paper also characterizes the load-deformation relationships, and statistically evaluates several stress-strain models proposed by different researchers. It was found that they coincided with test results in the elastic stage, but for the description of the decline and strengthening stages, each model is quite different and has different applicable scope.
