高层框剪结构梁柱节点混凝土强度验算研究

THE STRUCTURE OF HIGH STOREY FRAME AND SHEARING STRESS THE VITAL LINK POINT OF ROOF BEAM AND POST THE STRENGTH OF THE CONCRETE THE RESEARCH OF THE EXPERIMENT AND CALCULATE

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。

Using of the theory of multiaxial intensity and the theory that the longitudinal steel in the beam and in the column can improve the joint intensity, it is calculated, then analyze the actual axis compress stress of the joint of side column and corner post, and check the anti-seismic bearing capacity of the concrete beam-column joints, and work out a solution that the concrete of the column could be poured together with the beam and slab when the difference of the concrete strength of the column with that of the beam and slab no more than three grades.
