摘　　要：针对某超高层建筑中采用的圆钢管混凝土斜柱结构,建立了该类结构力学性能分析的有限元计算模型,并进行试验验证。在此基础上,初步分析圆钢管混凝土短斜柱钢管与混凝土之间的组合作用及破坏形态的特点。Aimed at the inclined concrete-filled steel tubular columns with circle sections in an existing skyscraper,finite element model was set up on the machanical behaviour of this structure.A set of test data was used to verify the finite element model.Generally,good agreement was achieved.Based on the finite element analysis,the interaction between steel tube and concrete,as well as failure mode was primarily analyzed.
