Abstract

Earthquake as one of most dangerous disaster could cause many damage to the city. To overcome this problem, many scientist and engineering try to development some new technology, as the result, damper and base isolator has come out for building construction. This project is reporting the investigation about effect of implementing damper device in seismic response of high rise building. for this purpose, a high rise 27 story structure is considered and three finite element models are developed include of structure without having any damper, structure with viscous damper and structure with base isolation. All the model will use same materials for the frame and under the same seismic load which is EI-centro earthquake load. The evaluate for model will base on: displacement, joint reaction for force and moment, the joint acceleration, the frame axial force, shell area for the structure and link axial force. After the evaluation, the compression between three models will be discuss in terms of displacement, frame axial force, and base reaction to study the advantage for damper and base isolator. As the result, all the properties for three models has been shown, and according to the compression, the damper shows good ability in control the displacement while base isolator could help to reduce the axial force for the frame and base reaction forces and moments. Therefore, it is recommended to have economic consider to analysis and get the suitable choice for seismic design.
