Static 3 point bending tests, with a total of 104 specimens, were carried out to study the bending performance of laminated bamboo board in and after exposure to high temperature from 20℃ to 225℃. The test results show that the bending strength, elastic modulus and ductility coefficient of laminated bamboo board in and after exposure to high temperature decrease with the increase of the temperature. However, except for ductility coefficient, both bending strength and elastic modulus of laminated bamboo board in exposure to high temperature are lower than that after exposure to high temperature. A statistical regression based model, as a function of the temperature, is developed and evaluated for prediction of the relative bending strength of laminated bamboo board. The predicted empirical results are consistent with the experiment values.
