| Abstract: |
| By using the performance of the model foundation,grid division and bring pressure to bear on,the model of finite element on small concrete hollow block has been built up based on software of ANSYS.The major factor which affected the non-linear mechanical properties of small concrete hollow block has been analyzed,including:(1)different stress-strain relations;(2)concrete strength grade.As a result the corresponding stress and strain under the given condition have been gained.Finally analogue result of mechanical properties of the small concrete hollow block by using non-linear and the linear elasticity analysis has been advanced,and the advantage of non-linear analysis has been advanced too.It will offer the useful help for further research. |
