外粘钢板加强钢筋混凝土梁的性能分析──完全卸载梁的加强

Behavior of Reinforced Concrete Beams with Externally Bonded Steel Plates

依据平截面假设，对外粘钢板加强钢筋混凝土梁正截面强度进行分析，其中包括梁在卸载后粘钢板，再重复加载至破坏的整个变形过程分析；外粘钢板面积对梁弯曲承载力的影响；原始配筋率对梁承载力提高幅度的影响；混凝土强度等级以及钢筋级别的影响。通过四根梁的实验，验证了理论分析结果。

Based on the assumption of plane deformation of the cross section, the research wascarried out on the cross -- sectional strength of reinforced concrete beams strengthened by externallybonded steel ptates. The research includes: the cross -- sectional deformation of the beams with orwithout bonded plates while loading and unloading, the effects on beam strength of steel plate area,initial steel ratio, type of reinforcement, etc. Four beam tests were carried out and verified about thecorrectness of analysis.
