混杂纤维加固混凝土方柱的轴心受压试验研究

Experimental Study of Axially Loaded Concrete Rectangular Columns Strengthened with Hybrid FRP Sheets

进行了素混凝土柱、碳纤维加固混凝土柱、玻璃纤维加固混凝土柱和碳纤维与玻璃纤维混杂加固混凝土柱的对比试验研究 ,以探讨各种柱的工作机理和破坏特征。试验结果表明 ,加固时混杂使用两种纤维 ,可使两种材料扬长补短 。

A loading comparison experimental study including CFRP,GFRP and CFRP GFRP hybrid strengthened concrete prisms is carried out to analyze their working mechanism and failure feature.Test results show that the CFRP GFRP hybrid composite could carry forward the advantages and overcome shortages of the materials,leading to a significant increase of the strengthening efficiency.
