This experimental study aims to investigate the seismic performance and torsional stress properties of the timber shear wall structure with eccentricity. Static loading tests were carried out using two specimens made from traditional timber construction. The dimension of the specimens were one-story system, 3.64m x 5.46m in plan and 2.86m in height. In addition, the horizontal diaphragm had two specifications with rigid and flexible floor. And the enforcement displacement which exceeds 1/5rad. of the story drift angle were applied on Y1 wall line in X-direction. From these results, the following conclusions were obtained. 1) The initial stiffness and maximum story shear force of specimen with rigid floor was larger than one with flexible floor. 2) When the floor stiffness of specimen became lager, the abilities of the horizontal resistant force for each wall line could be brought out enough. 3) The magnifications of stress properties for each wall line, floor, column-sill connections and so on were shown.
