Abstract

Multistoried building structures designed according to conventional methods result in low earthquake resistances. Seismic isolation bearings are considered an effective solution for the structure located in the earthquake areas. The paper presents a simplified procedure to calculate the isolated building according to the Vietnamese code. The bilinear equivalent model was employed to determine the properties of the isolator. Three-dimensional models of a typical building structure were selected to evaluate effects of the isolator. The modal analyses and time history analyses were performed using Etabs V17, with the input record taken according to the earthquake ground motion in Hanoi. The result shows the high effectiveness of isolator on reducing seismic effects.
