竹筋夯土墙单调水平荷载非线性有限元分析

Nonlinear FEM analysis of rammed-earth walls with bamboo bars under monotonic horizontal load

应用有限元分析软件ANSYS中的Solid65和Link8单元建立竹筋夯土墙的数值分析模型,并对其进行单调荷载下的数值计算,得出了竹筋夯土墙的抗侧承载力、裂缝形态、荷载位移曲线和延性。将数值结果与试验结果进行对比,结果表明,有限元法分析竹筋夯土墙具有较高的精度。

Numerical models of rammed-earth walls with bamboo bars under monotonic horizontal load were builded using Solid 65 and Link 8 in the commerical finite element software ANSYS,and then analyzed.Lateral resistence capacities,crack shapes,load-displacement curves and ductilities of the rammed-earth walls with bamboo bars were reached.By means of comparing the analytical to experimental results,it can be concluded that analysis of rammed-earth walls with bamboo bars using FEM has a high precision.
