由于柱与梁板之间的分隔存在一定难度，施工中习惯于在节点区统一采用楼盖的混凝土强度进行浇注，此时若柱、梁的混凝土强度等级相差较大，就将造成节点区混凝土强度达不到设计要求，节点区的承载力是否能满足要求成为工程技术人员最关心的问题。本文以某酒店框架节点承载力检测鉴定为例，在参考国内外相关经验的基础上，引入节点区混凝土“折算强度”的概念，较好地解决了节点区混凝土强度的取值问题，较准确地鉴定了节点的承载能力，为相关类似检测鉴定工作提供了参考。

Because separating column and beam-slab exist certain difficulty, accustomed to utilize unified the strength of floor concrete to pouring in joint construction. If the concrete strength grades of column and beam have large difference, the concrete strength of joint area can＂ t meet the design requirements, bearing capacity of beam- column joint whether or not satisfied the requirements cause the most attention to engineers. In this paper, we take the inspection and appraiser for the bearing capacity of beam-column joint of the hotel as an example, based on consulting some domestic and foreign experience concerning this subject, introducing the concept of ＂ discount strength ＂ of the joint area, to solve the problem of the strength concrete value ,giving more accurate result of bearing capacity of beam-column joint, providing a certain reference action for similar appraisal work.
