【摘要】 根据建筑的不同年限以及功能需要的新要求,提出了4种组合砖柱加固设计的试验方案,即钢丝网、钢筋笼、槽钢及CFRP-砖砌体组合柱。通过10根组合短柱的轴心受压试验,比较研究了以上4种不同材料及不同组合形式下砖柱的相关力学性能。试验表明:这4种加固方式都能有效地提高轴心受压短柱的承载力,柱的延性得到显著改善。更多还原

【Abstract】 Four new design models for combination of brick columns are brick columns wraped with steel wire,reinforcement cage,channel and CFRP are established to adapt to the development of years and functions of retrofitting.An experimental study on the mechanical properties of the composite column is conducted for 10 composite columns.The effect of materials and combinations on the mechanical properties of the composite column are discussed.The tests show that the four reinforcement approachs effectively raise the bearing capacity of the short column under axial compression and the ductility of the column improves well too.更多还原
