## 4 Conclusions  
The results derived from this research show the effectiveness of the use of the base isolation kinematic device (BIKD) system, presented by [PERSON] et al. [13]. For the analyzed scenario, we obtained a reduction in the target responses of maximum base shear load, and drift and displacement of the top storage level, of 90%, 86% and 85%, respectively.  
With the implementation of the BIKD system, the maximum displacement of the highest level of the rack in the direction parallel to the aisles, did not exceed 6 cm. This implementation resulted in a reduction of 85%, compared with the same racks that had a fixed support condition at the base. This implies that such an isolation system can reduce the response of racks, even in their most flexible direction. The above represents an advantage over the isolator described by [PERSON] et al. [11]; the BIKD system studied here allows the structure to be isolated from earthquakes in any horizontal direction. This has the benefit of reducing the response in the directions parallel to the aisles and across the aisles. This advantage offers security for both clients and workers who frequent these structures, avoiding the possibility of colliding with adjacent racks.  
It was observed that, with the use of the BIKD system, the industrial storage racks must be designed practically with the minimum requirements of the current standard (NCh2369 for Chile). The results showed a reduction of one order of magnitude in the normalized maximum base shear load, with respect to the FBR.  
The height of the BIKD, \(H_{iso}\), was the parameter that most influenced the maximum base shear load. For values \(H_{iso}\) < 0.5 m, this affected the lateral stiffness of the isolation system for large displacements. In isolators with \(H_{iso}\) > 0.5 m, their lateral stiffness remained practically independent of this parameter, so there was no benefit of using a greater height in the isolator. However, with \(H_{iso}\) < 0.5 m, the over-stiffening to the isolation system increased the demand for base shear load. Therefore, the use of isolators with a height close to 0.5 m, and no higher, is recommended.  
Finally, we determined that the parameters that had the greatest influence on the maximum displacement of the top of the racks and floor drift were the number of storage levels (\(N_{sl}\)) and the height between storage levels (\(H\)), in both FBR and BIR. This is due to the flexibility in these structures having a great influence on their response. Increasing these parameters contributed to greater flexibility. Consequently, the parameter with the least influence on the response of the system was the length of the rack in the direction parallel to the aisles (\(B\)).
