基于Solid65和Solid45有限单元的素夯土墙体数值建模及计算分析
Rammed-earth Wall Numerical Model and Calculation Analysis Based on Solid65 and Solid45 Finite Element
【摘要】 采用大型有限元软件ANSYS10.0中的Solid65和Solid45两种单元类型,对单调水平荷载下素夯土墙抗震性能进行了计算分析.计算结果和试验结果进行比较,从中选择合适的单元类型和破坏准则,为进一步计算分析木柱梁-土坯组合墙体的抗震性能奠定建模基础.
【Abstract】 Seismic behavior of rammed-earth wall under monotonic horizontal load is analyzed using Solid65 and Solid45 in the commercial finite element software ANSYS10.0. The work in the paper is to choose proper element and failure criteria from comparison between calculation and test results and to lay the foundation for the analysis on seismic behavior of wooden column and beam-adobe walls.
