Design & Comparative Analysis of Application in Earthquake Resisting RC Structures & LRB Structure

Abstract

Adherence to building codes prescribed by the government for specific regions, especially in earthquake-prone areas like Japan, Indonesia, and California, is vital for ensuring structural safety. Techniques such as lead rubber bearings (LRB) have been employed to minimize seismic vibrations by enabling the foundation or load-bearing structure to move in response to ground motion. Additionally, reinforced concrete (RCC) frameworks, with prescribed designs for transmitting loads to foundations through interlinking, have significantly improved earthquake resistance in modern structures. This study focuses on analyzing, designing, and estimating high-rise structures across various seismic zones, comparing traditional earthquake-resistant structures with those incorporating LRB technology. A comparative analysis of construction costs between these two methods will be presented, with the aim of determining the most economical and structurally safe approach. Base isolation, a key method discussed, involves the installation of support mechanisms that decouple the building from earthquake-induced ground motion, filtering seismic forces and reducing structural acceleration. This method has been proven highly effective over the past several decades, as it allows the structure to experience minimal movement despite significant ground motion during an earthquake.
