- Abstract:
- Based on the experimental study and inelastic theory, the ultimate flexural capacity of steel encased concrete composite beams are derived.The difference between steel encased concrete composite beams with full shear connection and beams with partial shear connection, together with the relationship between the inelastic neutral axis of steel parts and concrete parts, are considered in the formulae.The calculation results of the eight specimens with full shear connection and the three specimens with partial shear connection are in good agreement with the experimental data, which validates the effectiveness and efficiency of the proposed calculation methods.Furthermore, the nonlinear finite element analysis of the ultimate flexural capacity of the steel encased concrete composite beams is performed.Nonlinear material properties and nonlinear contact properties are considered in the finite element analysis.The finite element analytical results also correlate well with the experimental data.
- 基于外包钢-混凝土组合梁的试验研究和塑性理论, 按照钢梁和混凝土塑性中和轴相对位置的不同, 分别推导了完全剪切连接和部分剪切连接的外包钢-混凝土组合梁的正截面极限抗弯承载力的计算公式, 并对外包钢-混凝土组合梁进行了非线性有限元分析, 分析中重点考虑了材料非线性和接触非线性.8根完全剪切连接和3根部分剪切连接试件的正截面极限抗弯承载力的计算结果及有限元分析结果与试验结果吻合良好.
