摘　　要：采用94个试验方案,研究了泡沫铝填充矩形镀锌钢管在静态压缩下的性能。对试验结果进行分析可知,矩形泡沫铝填充镀锌钢管在静态压缩过程中经历了弹性阶段和屈服平台阶段,其平均压溃载荷、极限压溃载荷和吸能能力随着泡沫铝相对密度和钢管厚度的增加而增加,而其受构件长度的影响较小,特别是平均压溃载荷几乎无变化,极限压溃载荷随构件长度增大而略有减少。同时将试验结果与理论公式进行了比较,两者数值非常吻合。The properties of aluminum foam-filled rectangular galvanized steel tube under static compression was studied by 94 test schemes.The analysis of test results shows that the aluminum foam-filled rectangular galvanized steel tube goes through the elastic stage and yield platform stage in the static compression process.Its average crushing load,ultimate crushing load and energy absorption capacity increase along with the increased relative density of aluminum foam and the increased thickness of steel tubes,but with a relatively little effect of the component length and particularly almost no change to the average crushing load,and the ultimate crushing load decreases slightly with the increase of component length.At the same time,the test results are compared with the theoretical formula,which demonstrate that the two values are in good agreement.
