Analysis and Comparison of High Rise Structure with Base Isolation and Dampers

Abstract

As a consequence of building collapses and other structural damage, the number of lives lost due to earthquakes has risen dramatically over the last several decades across the globe. Such destruction during earthquakes is undeniable proof of the dangers posed by such events to buildings and other facilities, including homes, hospitals, and schools. It was crucial to conduct this research to ensure the efficacy of technology like base isolation and dampers in preventing damage to buildings during tremors.
The goal is to ensure the structure doesn't collapse when subjected to lateral pressures. The readings are recorded, compared, and analyzed using response spectra. Recent years have seen extensive focus on enhancing the wind and seismic responses of buildings and bridges via the study and development of structural control systems including passive control system, active control system, and semi active control system. There is no need for electricity to oper-ate a passive control system. Active control systems rely on internal sensors and a constant supply of external electric-ity. Both methods are suitable for usage against earthquakes and high wind speeds. There is no way to completely prevent natural catastrophes from happening.
Applying a base isolator and different dampers such a friction pendulum, fluid viscous, or visco elastic significantly reduced the displacement and drift values by 20-30% and 10-20%, respectively. Such measures prevent damage to the building and save lives during earthquakes and other events with high lateral stresses.
