摘要：为了进一步完善外包钢加固环形混凝土电杆的受弯承载力计算方法，基于空心钢管混凝土结构理论，考虑环形混凝土电杆纵向受力钢筋对加固后构件受弯承载力的贡献，利用ABAQUS软件，建立有限元计算分析模型，分析了外包钢强度和厚度对加固构件受弯承载力的影响规律。结果表明，采用外包钢加固环形混凝土电杆，受弯承载力随着外包钢的壁厚和强度增大而增大。将环形混凝土电杆纵向受力钢筋等效为外包钢，根据空心钢管混凝土结构理论，计算外包钢加固环形混凝土电杆的受弯承载力，其计算结果与有限元计算结果进行比较，由此确定截面面积等效系数为0.4，从而建立了实用的受弯承载力计算公式。 Abstract: In order to further perfect the calculation method for flexural capacity of circular concrete pole strengthened with external steel clad, based on the basic principles of hollow concrete-filled steel tubular structures, taking longitudinal steel bars into consideration, finite element analysis models were established with ABAQUS software, and influence rules of strength and thickness of external steel clad were analyzed. The results show that the flexural bearing capacity of circular concrete pole strengthened with external steel clad increases with the increase of the wall thickness and strength of the external steel clad. Under the condition that longitudinal steel bars are equivalent to external steel clad, flexural capacity of circular concrete pole strengthened with external steel clad was calculated. The calculation results were compared with the finite element analysis results so as to determine the cross-sectional area equivalent coefficient, and the area equivalent coefficient was calculated as 0.4, thus a pragmatic calculation method for flexural capacity of circular concrete pole strengthened with external steel clad was put forward.
