The research of anti-seismic control experiments of spatial reticulated shell structures

摘要

The large spatial reticulated structures belong to vibration and defects sensitive structures when vibrations will be easily produced under dynamic loading actions,and dynamic failure accidents will be caused.The application of the piezoelectric smart material in structural vibration control was researched with the shaking table test of active seismic control simulation of the spatial reticulated shell model structure.The results show that the piezoelectric actuators optimally arranged can effectively decrease earthquake responses of the structure,so it is a good active seismic control method.
