修复项目通常需要增加现有混凝土结构内构件的承载能力，这些构件因使用变更、原始设计或施工缺陷或退化导致的荷载需求增加而不足。此类加固通常包括提高抗剪承载力。

Rehabilitation projects often involve the need to increase the load-carrying capacity of members within existing concrete structures that are deficient due to increased load demand associated with change of use, deficiencies in the original design or construction, or deterioration. Such strengthening often includes increasing shear capacity.
