Abstract：The ancient wood structure subject to accumulative deformation under long-term vertical load. Aiming to solve the problem of plane stress for the ancient building’s wooden column under vertical load, analytical solutions of the stress, displacement component and the yield load are proposed by using elasticity mechanics. The semi-inverse solution is combined with the equivalent load method to get the equivalent simplification of the accumulative deformation column. For the semi-rigid characteristic of the ancient building’s terminal part, the displacement and stress boundary are adjusted to solve it. The results show that the lateral deflection of the column cross section has a great influence on the sectional compressive stress and a smaller influence on the lateral displacement at terminal part. At the same time, the semi-rigid joints’ nonlinearity characteristic affects the sectional compressive stress significantly. The influence of accumulative deformation on the yield load of the wooden column is discussed through comparing the numerical simulation by Ansys with the theoretical formula, which are mutually consistent. This paper has referential significance on the state evaluation of wooden column’s accumulative deformation under long-term vertical load.
