In traditional timber frame structure analyses, joints of timber members are generally idealized to the semi-rigid springs, and thus, it is one of the most essential subjects how to establish and decide the characteristics of the springs appropriately. In this paper, 2D- and 3D-isoparametric finite element analyses considering contact problem are applied in order to trace and examine wooden behavior of compressive strain inclined to the grain. Outline of the present approach is summarized. Some numerical tests are performed, and influence and effect of the material constants and the size of specimen on the wooden behavior are shown and discussed. Especially, it is cleared that Young's modulus of the direction inclined to the grain is most effective on the wooden behavior as compared with shear modulus, Poisson's ratio and so on.
