The vertical modal frequency of long-span hangar roof distributes densely and its vertical seismic response is very significant. Analysis of vertical seismic response control method of long-span hangar roof was carried out.Combining with the dynamic characteristics of long-span hangar,damping method by setting tuned mass damper was proposed. Corresponding calculation analysis was carried out and damping effect of the roof joint vertical seismic response was studied under time domain and frequency domain. Furthermore,multiple tuned mass damper( MTMD)was put forward for shock absorbing of long-span hangar. Damping effect of structure with MTMD of different parameters combination was compared under frequency domain. Results show that the spectrum characteristics of earthquake waves have significant influence on the damping effect. The reasonable damping method should be determined combining with the structure dynamic characteristics and ground characteristics.
