Effect of inclination damage on the seismic performance of Dou-gong and timber frame systems: Experiments and finite element analysis

Key Points

• Seismic performance diminishes significantly due to inclination damage, impacting structural integrity.
• Experiments and finite element analysis demonstrated that inclination damage reduced overall system strength by 30%.
• Structural observation showed that dou-gong systems were more adversely affected than traditional timber frame systems.
• Further studies are needed to explore design modifications to enhance the resilience of timber structures under seismic conditions.
