摘　　要：如何评估带穿透性非结构性裂缝混凝土构件的承载能力,是结构检测鉴定中的重要内容。基于构件接缝与穿透性非结构性裂缝实际工作状态的相似性,对已有构件接缝的相关知识进行了归纳总结,指出了现行规范中带裂缝构件承载能力评估方法存在的缺陷。其成果有助于对规范相关条文的进一步完善。How to appraise the load-bearing capacity of concrete member with non-structural penetration crack is an important issue for structure appraiser. Based on the similarity between the construction joint and non-structural penetration crack , the article gave a summary of the issued knowledge for construction joint , and pointed out that there exists some shortcoming in the appraisal for cracked concrete members＇ load-bearing capacity in the applying specification codes. The result is favorable to improve this situation.

关 键 词：裂缝 接缝 承载能力 混凝土结构
