Seismic Performance Evaluation of Damaged Ancient Timber Structures with Looseness Mortise-Tenon Joints
In order to investigate the seismic performance of damaged ancient timber structures with looseness mortise-tenon joints, the shaking table test of an intact ancient timber structure was carried out. The experimental model’s failure modes, main modal parameters, and dynamic response curves were investigated. In addition, the finite element models (FEMs) with looseness mortise-tennon joints were built by OpenSees, and the natural periods, acceleration, and displacement time history curves of intact FEM and experimental model are compared. Moreover, incremental dynamic analysis (IDA) of damaged models was performed, where the ground peak acceleration (PGA) and maximum inter-story drift ratio θ max are taken as intensity measure (IM) and damage measure (DM) of the motions of the ground, respectively. The seismic fragility of damaged models was studied by probabilistic seismic demand analysis to evaluate the seismic performance of the damaged structures from the perspective of probabilistic.
