不同强度等级混凝土框架节点分类置换技术研发与应用

Development and Application of Different Strength Grade Concrete Frame Node Classification Replacement

高层建筑常常对竖向结构(柱)与水平结构构件(梁、板),采用不同强度等级的混凝土设计,为确保高层建筑现浇框架节点施工质量,结合施工实践,我们对不同强度等级的现浇框架节点施工进行了专题研究。

High-rise buildings often use concrete designs of different strength grade for vertical structure （col- umn） and horizontal structure （beam, plate）. To ensure the cast-in-place framework node construction quality of high-rise buildings, taking construction into consideration, we conducted a special study on construction of cast-in-place framework node with different strength level.
