PurposeIt is necessary to study the behavior of embedment in order to specify mechanical behavior of timber structures. The embedment of timber is one of the most important and basic factors of timber structures. In this paper, bearing between timber beam and timber column is investigated carrying out embedment tests parallel to grain.MethodBearing tests between timber beam and timber column were carried out using glulam timbers, made of Douglas Fir. The tests were classified as two types, using uniformly distributed embedment and triangular distributed embedment. In these tests, depth and width of beam, distance from end, distance from edges and depths of column are important parameters to accurately model the behaviors.ResultEffects of parameters for glulam timbers are revealed after bearing tests. Mechanical models for bearing test of glulam timbers enable us to represent the effects of each parameter.
