通过实验研究了圆形泡沫铝填充钢管构件在静态压缩下的性能.对本试验范围内的结果进行分析可知,在外围钢管厚度较小时,在静态压缩过程中圆形泡沫铝填充钢管构件发生局部屈曲变形,压缩变形曲线现为弹性阶段和屈服平台阶段;在外围钢管厚度较大时,圆形泡沫铝填充钢管构件发生整体失稳,压缩曲线在经历弹性阶段后,进入弹塑性屈服阶段,到达峰值荷载后,构件承载力迅速下降.在试验基础上,提出了圆形泡沫铝填充钢管构件的平均压溃载荷和极限压溃载荷的设计公式,同时将试验结果与理论公式进行了比较,两者数值较为吻合.
Study on the static compression property of circular foam aluminum-filled steel tubes
The performance of circular foam aluminum-filled steel tubular members under static compression was studied experimentally.By analyzing the results within the scope of this test,it can be seen that when the thickness of the peripheral steel tube is small,the circular foam aluminum-filled steel tubular members have local buckling deformation during the static compression process,and the compression deformation curve turns into elastic stage and yield platform stage;When the thickness of the peripheral steel tube is large,the circular foam aluminum-filled steel tubular member will lose its stabili-ty as a whole.After the compression curve goes through the elastic stage,it enters the elastic-plastic yield stage.After reaching the peak load,the bear-ing capacity of the members will decline rapidly.On the basis of the test,the design formulas of the average crushing load and the ultimate crushing load of the circular foam aluminum-filled steel tubular members are proposed.Meanwhile,the test result is compared with the theoretical formula,and the two values obtained therein are relatively consistent.
