The purpose of this paper is to evaluate the mechanical properties of wooden moment resisting joints with serrated surface. In order to evaluate the basic characteristics of the joints with serrated surface, this paper proposes the mechanical models which can describe stiffness, yield strength, maximum strength and maximum deformations for shearing behavior of the serrated surface joints. The proposed model is verified with the shearing test results considering the pitch and slope angle of serration. Based on the proposed mechanical model, the load-deformation relationship of the proposed moment resisting joints with serrated surface is presented and verified with the test results. The results obtained in this paper are as follows: 1) Stiffness, yield strength and maximum strength of shearing joints with serrated surface can be evaluated by Eq.(8), (9) and (13). 2) Load-deformation relationship of the moment resisting joints with serrated surface can be described with Eq.(21). 3) The results evaluated by the proposed mechanical models agree well with the test results.
