偏压木构件的极限承载能力的研究

A Study of Ultimate Loading Capacity of Eccentric Compressed Timber Column

按强度确定偏压木构件的极限承载能力，计算中考虑了构件的二阶弯矩和截面抗弯的弹塑性工作。文中提出了偏压构件折断时，跨中央最大破坏挠度的近似理论计算方法；并导出了矩形截面偏压木构件的破坏挠度计算公式。所有的理论计算结果均与试验数据吻合良好。

In this paper, ultimate loading capacity of eccentric compressed timber column and elastic-plastic behaviour of the material of the cross section are considered.An approximate theoretic method dealing with the maximum mid-span deflection of the column when breaking is advanced.As a result, a formula calculating failure deflection of the rectangular cross section is derived. The results of theoretic calculation are well coincident with those of tests.
