Lastly, in accordance with the actual situations of the prototype structure of mosque pagoda, based on the similar relation of model experiments, a model structure of mosque pagoda with a similar coefficient of 1/10 is designed and fabricated. Earthquake simulating shaking table tests are performed on the model structure of pagoda in the cases the AB type passive control system with SMA dampers is erected or unerected. The leading earthquake responses like the relative drift at the top of the main tower and the small tower, interstory drift ratio, acceleration, and cracking process of the pagodas body etc. are studied. The operational behaviors involving the deformation capacity and energy dissipation capacity is tested for passive control system with SMA dampers under the earthquake excitation, and the corresponding control mechanism and regularity is also analyzed. Furthermore, the performance changes and protection effectiveness is comprehensively evaluated while the model structure of pagoda is seismically protected or not.
