（汕頭大學(xué)土木系 515063）[提要] 進(jìn)行了素混凝土柱、碳纖維加固混凝土柱、玻璃纖維加固混凝土柱和碳纖維與玻璃纖維混雜加固混凝土柱的對比試驗研究，以探討各種柱的工作機理和破壞特征。試驗結(jié)果表明，加固時混雜使用兩種纖維，可使兩種材料揚長補短，有效提高加固效率。
[關(guān)鍵詞] 混雜纖維 碳纖維 玻璃纖維 混雜效應(yīng) 混凝土方柱A loading comparison experimental study including CFRP, (JFRP 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.
