EARTHQUAKE RESISTANT TECHNIQUES AND ANALYSIS OF TALL BUILDINGS

The tall buildings are more flexible than the shorter buildings and they are sensitive to a different frequency range in the earthquake excitation. The earthquake success of tall buildings is reinforced by studies using average properties of earthquake and typical properties of tall buildings and there are no special earthquake hazards that arise simply as a consequence of height. The purpose of this paper is to discuss about different analysis methods, base isolation and soil structure interaction. Analysis method is used for a large variety of tall building configurations comprising slabs, beams, columns, foundations, walls, etc. Base isolation is a collection of structural elements which should substantially separate a superstructure from its substructure resting on a shaking ground which protects the integrity of building or non-building structures. It is one of the most powerful equipment’s of earthquake engineering which uses the passive structural vibration control technologies. Soil Structure Interaction is the process in which the response of the soil influences the motion of the structure and the motion of the structure influences the response of the soil. General goal of the Soil Structure Interaction analysis is to calculate seismic response of structure bases on seismic response of free field.
