| Abstract: | An algebraic equation of unknown numbers An and W n is established according to theory of material mechanics and assuming properly the range of the stability coefficient φ of a concentric compression member based on the formulas and applicable conditions in GBJ5-88. The expressions of W n and A n, which could meet requirements are obtained respectively by solving this equation. Further more, an expression of the maximum edge stress σ b of the tension zone is also derived by physical and geometrical coordinative conditions, whose numerical solution is given by calculation methods, thus realizing the direct solutions of b or r of the member section for a wood structure. |
