## 7 Conclusions  
This paper presents and discusses a displacement-based procedure for designing ADSs for the seismic rehabilitation of existing buildings.  
The primary objective of this procedure is to achieve a specified target displacement, thereby limiting deformations and interstory drift while enhancing dissipation. A closely related benefit is a significant reduction in the base shear in existing foundations.  
The proposed procedure, which involves determining the stiffness and yielding force of the dissipative system, is relatively straightforward as it relies on static (nonlinear) analysis. However, it requires several iterations to reach convergence. Additionally, it can adapt to various challenging situations by working with existing structures, including irregularities in plans and elevations, low plastic limits, and other characteristics.  
This approach distinguishes itself from others by considering the contributions of the existing structure. Furthermore, it meticulously evaluates the contribution of the dissipative system to meet the required performance of the new global system: the existing building + the ADS. This procedure originates from a revision of a method for designing dissipative braces, and its effectiveness, based on nonlinear static analysis, has been demonstrated through the application discussed herein.  
The limitations of the proposed procedure are, mainly, in the assessment of structural capacity through the use of the pushover analysis. Therefore, the most relevant limitations are related to the simplification of dynamic effects (Pushover analysis simplifies dynamic effects by applying lateral forces incrementally along the height of the structure.) because although this approach is useful for capturing the global response of the structure, it may not accurately represent the local dynamic behavior, such as torsional effects, bounding between adjacent structures, or soil-structure interaction effects.  
It is important to emphasize how the designed intervention aims to achieve a structural system that is less susceptible to torsion and soil-structure interactions (in the existing component of the building).  
Moreover, because the accuracy of pushover analysis results depends on the selection of input parameters, such as lateral load patterns, the distribution of lateral forces, material properties, and boundary conditions, inaccuracies or uncertainties in these parameters can lead to unreliable analysis results. According to this, the connection between the S and the ADS is finalized to move the \"relevant\" nonlinear behavior (dissipation) in the dissipative device of the ADS, keeping the existing structure mostly elastic and regularized in terms of the stiffness distribution.  
Therefore, despite these limitations, the pushover-based procedure remains a valuable tool for the preliminary seismic retrofitting design of structures with ADSs. The proposed procedure provides engineers with a simplified, yet insightful, approach.  
Subsequent developments and applications will be the subjects of future work. However, the author believes that the proposed approach represents a substantial advancement in displacement-based design for retrofitting with dissipative systems, especially given the limited discussion on the use of dissipative towers in the existing literature. This approach is both theoretically simple and straightforward in execution, making it suitable for professional applications without requiring expertise in complex nonlinear dynamic analysis. Only common static pushover analysis is necessary.
