The single‐span timber frame has been subjected to near‐fault ground motion. The timber beam as a structural element has numerically been analyzed. The relationship between the acceleration histories of earthquake used in the numerical analysis with strain displacement has been discussed. For the analysis on acceleration histories of the earthquake, the specific part of acceleration histories of earthquake used in the numerical analysis has been zoomed in order to deeply analyze the effect of nonlinearity of acceleration histories to timber beam seismic response. The results have shown that the nonlinearity of acceleration histories of an earthquake before it reaches the peak is different compared with after reaching the peak. The nonlinearity of acceleration histories of an earthquake phenomenon has a direct relationship with the seismic response on timber beam and the influence to the energy dissipation and nonlinear deformation of the beam.
