【摘要】 针对震损砌体结构的加固需求,提出采用碳纤维布(CFRP)加固震损砖柱的方法.通过轴心、偏心受压试验,对碳纤维布(CFRP)条带满包加固震损砖柱的受压性能展开研究,对加固前后砖柱的承载能力、变形能力及碳纤维布(CFRP)条带的应变等进行对比分析,讨论了碳纤维布(CFRP)在砖柱受力过程中发挥的作用,在此基础上提出碳纤维布(CFRP)加固砖柱承载力计算公式.研究表明,碳纤维布(CFRP)加固震损砖柱效果良好,提出的计算公式与试验结果吻合良好.更多还原

【Abstract】 In order to meet the demands of reinforcement of earthquake-damaged masonry structures,a method for strengthening earthquake-damaged brick columns with carbon fiber reinforced plastics(CFRP)is proposed.Through the axial and eccentric compression tests,the compression behavior of earthquakedamaged brick columns strengthened by CFRP is studied.The bearing capacity,deformation capacity and strain of CFRP strip of the brick columns are compared with those of brick columns without strengthening.And the effect of CFRP under loading is analyzed.A formula for calculating the ultimate bearing capacity of earthquake-damaged brick column strengthened by CFRP is proposed based on experimental study.The research results show that the reinforcement effect of CFRP is very good and the proposed formula is reasonable.更多还原
