复合材料管-钢管约束混凝土组合柱的轴压性能
Axial compression performance of FRP tube-steel tube confined concrete composite columns
摘要
Abstract
Mechanical properties, failure mode, stress-strain curves and load capacity were analyzed by the axial compression experiments on concentrically compressed fiber reinfoced polymer ( FRP) tube-steel tube confining concrete composite columns. The results showed that the function of FRP tube was very small at the loading beginning, and the hoop stress increased quickly at the later loading stage. The load capacity was achieved by hoop rupture of FRP tube. Compared with experimental data,The existing stress-strain model of confined concrete had a great deviation for predicting ultimate strain of hollow composite columns. However, solid composite columns worked well. A simplified calculation method was presented to determine the ultimate loads of solid composite columns, and theoretical results agreed well with experimental results.关键词
