Non-Linear Time history Analysis of Tall Structures for Seismic Load Using Damper under Different Soil Conditions

Abstract

During major seismic actions, a significant amount of energy is induced to structures. This means by which this energy is dissipated, determines the level of structural degradation. Special emphasis is placed on avoiding loss of human lives due to the earthquake action. In order to achieve this, the structures are designed ductile so that energy is dissipated by the system’s elements by bending, twisting or degradation. This dissipative mechanism involves significant degradation of the structures thus leading to significant post-earthquake rehabilitation costs. If the amount of energy induced in the structure can be controlled or, if part of it can be dissipated mechanically by independent structures, the seismic response of the buildings is improved and the potential damage greatly reduced.
