Abstract

Earthquake is one of the nature’s greatest hazards, throughout historic time they have caused significant loss of life and severe damage to property, especially to Man-Made Structures. Therefore, it is necessary to provide special lateral load resisting design methods that improve lateral stability of the structures. Base Isolation is an effective method for earthquake resistant design to reduce vibration transmitted from ground to the structure. Bracing is a very effective and economical system which improves the seismic performance of frame by increasing the lateral stiffness and capacity of frames. Performance Based Plastic Design (PBPD) method has been recently developed to achieve enhanced performance of earthquake resistant structures. The design concept uses pre-selected target drift and yield mechanism as performance criteria and uses the concept of strong column-weak beam method. In the present study the attempt is made to understand the seismic performance of different lateral load resisting building, such as base isolated buildings, braced buildings, PBPD buildings. From this study It has been observed that all the methods have their own specialization in their performance criteria according to the requirement the designer should decide the method in terms economical, strength, aesthetic.
