In this study, to evaluate the influence of PΔ effects on the deformation performance of wooden house, the static lateral loading test to the large deformation region of the wooden frame structure is performed to the collapse. It is pointed out that the ratio of the bending deformations of column in the story drift angle is not so large, the additional shear force by the PΔ effect can be explained from the story drift angle in the experimental results. Finally, we propose the method to estimate the story drift angle when the lateral resistance force is lost from the story shear coefficient in the large deformation region (story drift angle is between 0.1 and 0.15rad).
