As there is no related specification for designing the laminated bamboo frame structure now, experimental study and analysis on the laminated bamboo columns will be done in this project. The methods such as experimental study, theory study and numerical simulation will be taken for the project. The basic mechanical properties as well as the influecing factors will be studied for the laminated bamboo lumbers, then the strain-stress relationship model and failure criterion will be set up. The long column and short column will be defined through experimental study and analysis. Then the inner relationship between the crack pattern, scale and extend law and the stress field changes will be studied. In addition, The failure mechanism for the axial compression long column and short column as well as eccentric compression column will be revealed. The quantitative relationship between the damage status and the design parameters will be established for the laminated bamboo building structure column. Finally, the load calculation model for the axial compression long column and short column as well as eccentric compression column will be put forward. Based on the experimental study and analysis, the design ways and suggestions will be proposed for the columns. The research results can supply experimental data and theoretical basis for developing the related codes and standards for the bamboo buildings and for the promotion and application of modern bamboo building structure.
