摘要:

采用基于纤维模型的分段分块的杆系结构有限元方法,推导了钢管混凝土压弯构件的弹塑性刚度矩阵,提出了计算钢管混凝土压弯构件弹塑性稳定承载力的计算模型,编制了相应的计算程序.采用提出的方法和程序,计算了圆管截面的钢管混凝土轴向受压、偏心受压长柱的弹塑性极限承载力,理论分析结果与文献报道的试验和理论结果吻合良好.

Abstract:

The elastic-plastic stiffness matrix of steel tube concrete bending members is derived by using the finite element method of segmented and block rod structure based on fiber model, and a calculation model for calculating the elastic-plastic stable bearing capacity of steel tube concrete bending members is proposed, and the corresponding calculation program is compiled. The proposed method and procedure were used to calculate the elastoplastic ultimate bearing capacity of the axial compression and eccentric compression long column of steel tube concrete with round pipe cross-section, and the theoretical analysis results were in good agreement with the experimental and theoretical results reported in the literature.
