碳纤维约束高强混凝土柱轴压力学性能试验

Experimental Study of Columns Reinforced by CFRP Under High Concrete Strength Level

进行了对C40-C60强度等级下46个混凝土短柱包裹不同层数CFRP布后的轴心受压试验研究。通过对试验结果的比对,研究了轴压短柱中CFRP布包裹加固中不同混凝土强度等级对以及不同CFRP布包裹层数对短柱轴压性能的影响,并从材料微观角度对加固效果的影响因素作出分析。

This paper managed an experimental study of 46 short compression. Specimens are made from different concrete strength columns reinforced by CFRP sheets under axial levels. The resuh illustrates factors such as concrete strength level and layers of CFRP wrapped that affects axial compression load capacity of short columns. And this paper also analysis factors that affect reinforcing effect from microscopic point of view.
