摘　　要：通过对后锚固钢梁加固钢筋混凝土楼板时楼板内力的分析,论述了后锚固钢梁变形对楼板内力变化的影响,提出了合理考虑后锚固钢梁变形的加固方法,并以一实例给予验证。本文内容可供类似工程的加固设计借鉴。Based on the analysis of the internal force of reinforced concrete plate strengthened by post- installed steel beam, the change of internal force of the plate due to the deflection of post-installed steel beam was discussed in the paper, and an strengthening method taking into account of that deflection was brought forward, which is validated by a practical project. The strenghthening method could afford references to similar strengthening projects.
