【提要】  采用碳纖維布分別對(duì)未加載及加載至破壞的實(shí)心粘土磚柱進(jìn)行環(huán)包加固，通過(guò)試驗(yàn)研究了碳纖維環(huán)箍加固的軸心受壓實(shí)心粘土磚柱極限承載力的提高幅度及其受力性能，并對(duì)其受力特點(diǎn)及影響其承載力、延性的因素進(jìn)行分析。試驗(yàn)結(jié)果表明，碳纖維布提供的緊箍力使實(shí)心粘土磚柱的強(qiáng)度和延性都得到較大提高。碳纖維布的輕質(zhì)高強(qiáng)、耐腐蝕等特性使其可以應(yīng)用在歷史性磚砌體建筑的加固工程中。
【關(guān)鍵詞】  碳纖維布  軸心受壓柱  加固  力學(xué)性能
Experimental Research of Axially Loaded Brick Columns Strengthened by CFRP/Tian Shui，Peng Shaomin，Gu Qian（School of Civil Engineering and Architecture， Wuhan University of Technology，Wuhan 430070，China）
Abstract:The mechanical property of CFRP strengthened solid clay brick short column under axial compression is tested. The experimental result indicates that the confinement offered by CFRP can improve the strength and toughness of column
greatly. CFRP can be used to retrofit historic brickwork for its many good qualities，such as light weight，high strength，noncorrosive.
Keywords:CFRP；axially loaded brick column；reinforcing；mechanical property
