Bending strength(MOR) of Chinese larch(Larix gmelinii) dimension lumber(grades Ic, IIc, IIIc and IVc for 40 mm × 90 mm × 4 000 mm) was obtained by full-size bending tests. Optimal probability distribution model for the MOR was investigated by the least square method. According to reliability theory, design values for MOR of dimension lumber with different grades were then determined. The goals of this study were to improve determination method for design values of dimension lumber strength and to provide scientific basis for safety design and reasonable application in wood building structures.
