The modeling characteristics of the reinforced concrete building prototypes are shown in Figure 4, with the aim of assessing the effectiveness of leaded rubber isolators (LRBs) in reducing the seismic response of these buildings. These prototype buildings are essential to our study as they enable us to simulate and analyze how LRBs influence the behavior of reinforced concrete structures under seismic conditions. Details of the LRBs used in this process are specified in Table 2.
