METHODS FOR ENHANCING THE BUILDINGS BEHAVIOUR AT SEISMIC MOTIONS

Résumé

Improving a building's behavior during seismic events represents a critical aspect of structural engineering, aiming to reduce damage, ensure safety and preserve functionality for the buildings. Several methods and technologies have been developed over the years to improve a building's
performance in seismic motions. These methods can be categorized into design strategies, damping systems, base isolation and retrofit techniques if they are applied to old buildings. A numerical analysis is performed to highlight the isolation characteristics of buildings and how the response is modified in the event of seismic motion. The results are presented in terms of displacements, velocity, vibration period and energy which are decisive
for defining the building's seismic behavior.
