摘要
进行了素混凝土柱(未加固)、两层单一碳纤维(CFRP)加固混凝土柱、两层单一玻璃纤维(GFRP)加固混凝土柱和两层碳/玻不同比例层内混杂纤维(HFRP)加固混凝土柱的对比试验研究,以探讨各种加固条件下试件的破坏过程和特征。试验结果表明,相对于单一CFRP加固混凝土柱,碳/玻HFRP加固混凝土柱在保证一定的极限承载力的前提下能显著提高其延性,同时降低加固的成本。
A comparison experimental study including the plain concrete column( unreinforced),single CFRP reinforced concrete column,single GFRP reinforced concrete column and HFRP reinforced concrete column with CFRP and GFRP in different proportion is carried out to analyze the failure process and characteristics. Test results show that,compared with single CFRP reinforced concrete columns,on the premise of ensure a certain degree of the ultimate bearing capacity,HFRP strengthened concrete column members have not only a higher ductility but also a low cost.
