| summary(En) : | 1) In this report are presented the results of a mathematical analysis of stiffness problems for Wooden Box-Beam under a few types of loading. The deflection of bending is obtained by the use of elastic strain energy function. From that  in the case of center-loading, end support, equation (4.1) is, if it is integrated for several integral variants x, y, z according to Fig. 1 and 3,  where P = the load applied to center of Box-Beam. δ = the deflection of center of Box-Beam, (max. defl.) 2) The wooden Box-Beams used in a preliminary experiment were constructed with Flange of Yezomatsu and web of 3 ply Lauan plywood (L, T, LT = 45° as parallel, perpendicular, and 45° respectively, to the grain of the face plies). 3) In the case of center-loading test the theoretical value δ/p calculated from equation (5.1.2) was almost the same as the experimental ones, and the agreement between experiment and theory can be regarded as reasonably satisfactory.
