The seismic and lateral resistance of column-and-tie wooden buildings based on mortise-tenon joint

摘要

The seismic and lateral resistance of column-and-tie wooden buildings was studied in this research. A simple mortise and tenon side joint model and an overall framework model were established. Earthquake and horizontal axial force were simulated by two independent jacks. The results demonstrated that mortise and tenon joints had deformation and stiffness degradation, the global slip of the framework and slip of the column footing increased with the increase of the load. The maximum global slip was 100 mm, and the maximum slip of column footing exceeded 30 mm. The global slip was small, suggesting good seismic and lateral resistance of column-and-tie buildings. The experimental results can provide some theoretical support for the reinforcement and development of column-and-tie wooden buildings.
