Research on Finite Element Model for Parallel to Bamboo Culms Axial Shear

For the issues of bamboo structure safety caused by parallel to bamboo culms axial shear, shear capacity test method is studied, parallel to bamboo culms axial shear capacity finite element model based on brittle fracture mechanics is proposed in the work. The results calculated by FEM are consistent with the experimental results, and the error is in 16% or less. The parallel to bamboo culms axial shear capacity finite element model established above can provide supports for bamboo culms wide engineering applications. The developed model has theory and engineering significance for digital bamboo building optimal design.
