摘　　要：简述了目前国内外梁柱节点设计现状,分析了存在的缺陷;经梁柱节点受力分析和多轴强度设计理论的建立,导入了边柱和中柱节点分别为二轴和三轴压应力工作状态的概念,并运用多轴强度理论和柱、梁纵向受力钢筋对节点强度提高理论进行计算,进而对边柱、角柱节点实际轴压应力计算分析,并对梁柱节点混凝土进行抗震承载力复核验算,得出了柱与梁板混凝土强度相差≤3级时,可随梁板混凝土一起浇筑的结论。科学定量地解决了近年来工程界一直争议的"梁柱节点是否能与梁板混凝土一起浇筑"的关键性技术难题。It is described the present state of beam-column joint design both at home and abroad,and the defects are also analyzed.Multiaxial strength theory is adopted to recheck the aseismic bearing capacity of the concrete for beam-column joints. It is finally concluded that if the strength of the column concrete of is 10～15MPa higher than that of a beam plate,then the concrete of the column can be poured together with that of the beam plate,which has solved the key problem that has been disputed by the engineering circle in recent years.
