摘要
碳纤维加固具有自重轻、抗拉强度高、易施工、耐久性好等优点,被广泛应用于加固钢筋混凝土结构,并开始推广应用于加固钢结构。采用碳纤维加固钢压杆,对其稳定承载力进行简化分析,并推导出加固后钢压杆临界荷载和稳定系数的计算公式。
The CFRP strengthening has the advantages of low density, high strength, facility, endurance, etc, so it has been widely applied to strengthen reinforced concrete structures. It is also applicable to the rehabilitation of steel structures. A simplified buckling analysis of steel compression members strengthened with CFRP is carried out, and formulae of the buckling loads and stability coefficients of the strengthened compression members are derived.
