摘要：

The method and equations for calculation of the stability coefficient of wood members in axial compression in the current Chinese code for design of timber structures only apply to members made of sawn or round timber, yet can not apply to members made of modern wood products such as imported sawn lumber and glued laminated timber, which are stress-graded. The methods for calculation of the stability coefficient in the design codes of various countries were compared and analyzed. Considering the characteristics of modern wood products, new and unified equations for calculation of the stability coefficient applicable to members made of various wood products were proposed, in which the traditional treatments of our country were kept. The constants in the unified equations were determined through regression with respect to different wood products, and the error in calculation of the stability coefficient was basically within 10%. Buckling tests of compression members made of SPF dimension lumber were conducted, and the buckling behaviour of the members was simulated with random finite element method. The results of the stability coefficient from tests, random finite element analysis and regression are well correlated, which verified the suitability and correctness of the proposed equations. The continuity and the consistency of design code method are kept and the need for design of modern timber structures satisfied. © 2016, Editorial Office of Journal of Building Structures.
