For the purpose to evaluate seismic performance of timber structures against severe earthquakes like as 1995 Kobe earthquake, it is desired to propose survivability limit state criteria and design method for them. Shaking table test of timber structures using JMA Kobe motion was conducted, and collapse of timber structures was simulated physically on the shaking table. The following aspects were obtained from the analysis of shaking table test. Load-deformation curves considering P-delta effects and non-linear damping factors were obtained from shaking table tests. Asymmetrical hysteresis model for timber structures was proposed from asymmetrical features on load-deformation curves. Process of energy absorption and distribution between terms in the equation of vibration was clarified. Relationship between capacities of energy absorption and collapse of structures was clarified. Energy-based evaluation method using capacity of energy absorption was applied to the test results. Energy-based design using Housner's assumption for timber structures was verified in shaking table tests. Energy-based design using Housner's assumption for timber structures was applied for survivability limit state criteria.
