《建筑工人》1998年第3期刊登了《高层框架结构混凝土施工一法》一文。该文提出:如果高层框架结构梁和柱的混凝士强度等级差距不大于 C5,可以同设计单位和建设单位协商,使梁板柱的混凝十强度等级统一,但只能提高等级;如果混凝土强度等级差距大于 C10,梁板柱一定要按照各自的混凝土强度等级进行浇筑,
In the 3rd issue of “Construction Workers” in 1998, a “High-rise Frame Structure Concrete Construction Method” was published. The article proposes that if the gap between the strength ratings of high-rise frame structure beams and columns is not greater than C5, it is possible to negotiate with the design unit and the construction unit so that the strength and ten strength grades of the beam-column column are unified, but only the level is increased; if the concrete strength level is different Above C10, beams and slabs must be cast according to their respective concrete strength grades.
