[摘要]以某实际超高层项目梁柱大偏心节点为例,定量分析了梁柱偏心所产生的附加弯矩、附加扭矩及对节点核心区抗剪承载力的影响。结果表明,对于该项目柱大梁小、柱强梁弱的实际情况,即使不采用梁端水平加腋措施,柱抗扭能力和节点核心区抗剪承载力都仍有较大富余,且柱端弯矩更小。

Abstract:Taking the beam-column joints with large eccentricity in a super high-rise structure as the example, the influence caused by beam-column eccentricity on additional moment, additional torque and shear bearing capacity of core joint area were analyzed. The results show that, for the actual situation of big column-small beams and strong column-weak beams in this project, even if there is no horizontal haunches on the beam ends, the torsion capacity of the column and shear bearing capacity of core joint area are still large enough, and the bending moment of column ends is smaller than those joints having horizontal haunches.
Keywords:beam-column joint; large eccentricity; shear bearing capacity of core joint area; horizontal haunch
