PET材料对双层钢管混凝土柱轴压承载力提升研究

On promotion of axial pressure loading capacity of double-layer steel pipe concrete column with PET material

从改善结构延性的角度,系统地研究了外包PET材料的双层钢管混凝土柱的力学性能,并通过试验得到了其轴压承载力增长的现象和规律,将试验研究结果与试验前理论计算结果进行了对比,验证了理论计算公式的准确性。

From proving the structureJ s ductility, the paper researches the dynamic performance of the double-layer steel pipe concrete column with the contracting PET materials, concludes the increasing axial pressure loading capacity and law with the test, compares the test research re-sults and theoretic calculation results before the test, and proves the accuracy of the theoretic calculation formula.
