In order to study the seismic effectiveness of the most commonly used support method for fixing figurine cultural relics， the full-scale shaking table tests of the seismic system （two types of figurine replicas with typical size and vulnerable materials and fixed measures of supports） were carried out. The seismic responses of the cultural relic replicas and the interaction between the cul? tural relic replicas and supports under different working conditions were obtained. The influence of the key body shape parameters of figurines， the clamping position of metal supports， the support size， the installation gap between cultural relic replicas and fixed measures on the movement state of cultural relics was discussed. The seismic effectiveness of support measures was evaluated and reasonable suggestions were put forward. It provided the necessary basis for the optimal design of fixed method for this type of cul? tural relics with the principle of safety and minimum intervention. The results showed that all the floating figurine replicas were overturned， which had a great risk of damage. The rocking responses of figurine replicas were effectively reduced after independent supports were used for fixation. As the ratio of the center of gravity height to the base width of the figurine replicas increases， along with the increase in their mass， the obvious plastic deformation or even the root fracture occurred in the case of smaller supports， resulting in overturning and damage of figurine replicas. At the same time， with the increase of the size of the supports， the im? provement of the fixation effect was limited. Based on the principle of minimum intervention for cultural relics， and considering the seismic safety and the art exhibition， the support size should be optimized. The rocking responses of figurine were controlled to some extent when its shoulder was fixed by the support， however， with the increase of the fixed position， the sliding response of the figurine was more obvious. The surface of the figurine was easily damaged because of the interaction between the support and the figurine. When the gap between the two was filled with silica gel cushion， the rocking and sliding responses of figurine replicas were reduced by nearly 40% and 50% respectively， the strain at the root of the support was reduced by nearly 40%， and the strain at the contact area between the figurine and the support was reduced by nearly 60%， which effectively improved the seismic effec? tiveness of support measures.
