A simple calculation method is proposed for predicting the elastic and plastic behavior of moment resistance timber frames without using non-linear numerical analyses by wire frame modelling. The behavior of timber frames which have multiple stories and spans can be calculated by hand or spreadsheets based on flexural stiffness of members and spring behaviors of joints. The accuracy of the calculation method have been verified by comparing calculation results with results of experiments and non-linear numerical analyses under several different conditions. This calculation method can be used for estimating the structural behavior of timber frames as well as numerical analyses.
