Comparison Of With Base Isolation And Without Base Isolation Building for G+15 High Rise Structures

Abstract

Reinforced concrete is a important construction material in civil engineering. This investigation serves as a case study to evaluate the ultimate capacity of the selected bearing system in reinforced concrete structures. The study aims to compare the performance between fixed base buildings and base isolated buildings. Specifically, the research focuses on assessing the appearance and ultimate capacity of the bearing system in both types of structures, aiming to provide insights into their respective behaviors under different loading conditions.Earthquake is one of the challenges faced which hampers the stability of the structure. The consequences of an earthquake can be far-reaching, resulting in significant loss of life and widespread devastation of infrastructure. However, there are various measures that can be implemented to mitigate the impact of earthquakes and minimize the resulting damages. Base isolation is one of the measures to reduce the impact of earthquakes. In this project we investigate how the fixed base of multistoried building is modified by base isolation.  Reinforced concrete is a crucial construction material extensively used in civil engineering. It plays a significant role in ensuring structural stability, especially when subjected to ground motion. To assess the performance of different building systems under seismic conditions, two analysis approaches are commonly employed: (1) Analyzing a building on a fixed base, and (2) Evaluating the same structure supported by an isolation system. By conducting these analyses, engineers can gain valuable insights into the behavior and effectiveness of various structural configurations in mitigating earthquake-induced forces. A structure was analyzed by using following methods: (A) Equivalent Lateral Force Method (B) Response Spectrum Method for investigate fixed base building and isolated base building with Lead Rubber Bearing.
