研究了一种新型纤维增强聚合物（FRP）筒填充超高性能混凝土（UHPC）混合柱的地震响应。基于5根uhpc填充FRP管（UHPCFFT）和1根参考混凝土柱（RC）的拟静力试验结果，提出了一种估算其最大地加速度能力的方法。所提出的分析方法可应用于任何拟静态试验。分析表明，与RC柱相比，带有薄FRP管的无钢UHPCFFT柱的最大地面加速度能力提高了20%。通过非线性动力学仿真进一步验证了结果。
The seismic response of a novel hybrid column made of a fiber-reinforced polymer (FRP) tube filled with ultra-high performance concrete (UHPC) was studied. A methodology was proposed to estimate the maximum ground acceleration capacity of five UHPC-filled FRP tubes (UHPCFFT) and one reference concrete (RC) column based on the results of their pseudo-static tests. The proposed analytical methodology can be applied to any pseudo-static test. The analysis showed 20% higher maximum ground acceleration capacity for the steel-free UHPCFFT column with a thin FRP tube, as compared to its RC counterpart. The results were further verified using a nonlinear dynamic simulation.
