A wooden prefabricated truss system utilizing Japanese medium- and low-quality timbers has been developed in order to promote the effective use of these timbers. The purpose of this study is to evaluate the effect of the dispersion of stiffness of members on the stress magnitude and displacement in designing the wooden prefabricated truss. Monte Carlo analysis revealed the maximum stress of the members to be 1.2 times greater than the stress analyzed by the standard Young's modulus (E_0) due to the dispersion of Young's modulus. The maximum displacement of nodes is also greater than the displacement analyzed by E_0. It is suitable to use the 5% lower limit of Young's modulus based on full-size tests of timbers considering the deformation of nodes.
