应用多重多枝子结构方法，对超高层钢筋混凝土结构的梁柱不同强等级混凝土节点，在考虑复杂钢筋配置的情况下，进行了具有十万多个自由度的有限元分析，得到梁柱节点的混凝土和钢筋的应力分布及应力集中区范围，为梁柱节点的合理设计提供了重要的分析结果．
By using the multi-branch sub-structure method, the finite-element analysis with more than 100,000 degrees of freedom was performed for the super-high-rise reinforced concrete structures with different strengths and grades of reinforced beam and concrete. The stress distribution and stress concentration area of the steel bar provide important analysis results for the reasonable design of beam-column joints.
