Finite element analysis on multi-storey brick-concrete structure influenced by mining induced deformation

摘要：

To study the anti-deformation characteristics of multi-storey brick-concrete structures in mining subsidence area, a piece of wall is analyzed using finite element method. We review the internal force as well as the deformation and stress of the structure by applying different deformation on the model. The results indicate that the tensile deformation influences the foundation ring girder stress evidently, and the curvature deformation mainly increases the stress of constructional column. However, a combination deformation doesnt lead to a linear superposition of the accessional force. The effect of the foundation slip layer is checked carefully. It is indicated that as the shear slippage of the layer cut off the pipeline of the earth surface deformation, the accessional deformation of the foundation ring beam and the wall decreases remarkably. The slip layer is efficient to alleviate the influences of tensile deformation, while sufficient to that of the curvature deformation.
