秸秆重组材梁承载性能的有限元分析

Finite Element Analysis of Bearing Capacity of Straw Reconstituted Timber Beams

采用ANSYS16.0软件对静力荷载作用下的秸秆重组材梁进行弹塑性有限元分析,根据分析结果得出梁的极限荷载,并运用力学理论推导出秸秆重组材梁的承载力计算公式。通过承载力公式计算结果与有限元分析计算值的对比,验证了有限元分析的正确性。

Using ANSYS16.0,the elastoplasticity finite element analysis of the straw reconstituted beam under static load is carried out,and a bearing capacity calculation formula is obtained based on the analysis result.Mechanical theories are used to deduct a bearing capacity calculation formula for straw reconstituted beams.Based on the calculation result of the bearing capacity calculation formula and the comparison between finite element analysis calculation values,the correctness of finite element analysis is verified.
