摘要
基于全截面塑性理论,提出了钢板混凝土(SC)组合墙压弯承载力计算模型。试验与有限元计算结果均表明,该计算模型具备精度高和简单实用的双重特点。有限元计算结果还表明,对于剪跨比小于1.0的SC组合墙,建立的压弯模型不再适用,原因在于剪力的耦合作用不可忽略,建议加强对小剪跨比SC组合墙抗剪承载力试验和机理的研究。
Based on the theory of plasticity, the calculation model of axial load-bending moment capacity of steel concrete composite （SC） walls was proposed. Test results and finite element calculations show that the calculation model has the twin advantages of accurate and concise. FEM results also indicate built model no longer applies for low shear-span ratio. Experimental study and theoretical analysis of shear resistance for low shear-span ratio SC walls should be conducted.
