Benefits of Using Different Types of Isolators

The purpose of this study was to investigate the combined use of two different types of isolators and their benefits when used together in buildings. A building model was constructed incorporating both Lead Rubber Bearing (LRB) and Elastic Slider Bearing (ESB) isolator types within the scope of the study. To generate earthquake acceleration records for structural analysis, specific soil parameters were selected from a defined region. The earthquake acceleration records were then fitted to the horizontal elastic design spectrum using Mathworks Matlab software. Finally, analyses were performed using the CSI ETABS structural analysis program. Given the absence of a re-centering feature in the elastic slider bearing, it is anticipated that its use alongside a lead rubber isolator would provide more favourable results. The analysis results indicated that the use of these isolator types together gave positive results, particularly in scenarios where the structures were subject to high axial loads and a longer construction period was desired.
