某工程转换层梁裂缝检测分析

Analysis of cracks tested in transfer floor beams of a building

结合重庆地区某工程实例,对下部为框架、上部为砖混结构的组合结构混凝土转换层梁开裂问题进行了分析和讨论,指出设计构造不当、大体积混凝土收缩、混凝土强度等级等因素对该转换层梁裂缝形成的影响,并提出了相应加固处理建议,其工程经验可供同仁参考。

According to a practical engineering example in Chongqing,the problems of crack are analysed in R.C.transfer floor beams of masonryR.C.composite structure.The influence of some factors on the cracks in transfer floor beams,including improper design and configuration,shrinkage of massive concrete,intensity grade of concrete,are put out in this paper.Suggestions of strengthening measures are submitted.The engineering experience is for reference to the colleagues in the fields of structure engineering.
