| dc.description.abstract | Over the past few decades, the concept of base isolation has gained prominence as a prospective methodology for safeguarding structures against severe seismic events and wind forces. Many international building codes have recognized its effectiveness and incorporated relevant sections. This paper aims to demonstrate the exceptional performance of Lead Rubber Bearing (LRB) isolation systems through an extensive parametric study. The study showcases a significant reduction in various response parameters and emphasizes the substantial energy dissipation capabilities of the LRB system. These compelling results underscore the urgent need to develop a novel design methodology for isolated buildings in alignment with Algerian seismic regulations, which currently lack provisions for this advanced technique. The research introduces an innovative approach for LRB isolators, employing the equivalent static method. This technique is characterized by its utilization of an iterative procedure for adjusting the isolator’s displacement in accordance with the mechanical and geometric attributes of the structure. To validate the proposed model, a comprehensive parametric study was conducted on a building designed in compliance with several international codes, including IBC 2000, Italian, Chinese, Japanese, Taiwanese, and Algerian codes. The results stemming from this innovative design methodology closely align with the requirements of these international codes, affirming its global applicability and relevance. | |
