Seismic Presentation of a Multi-Story Building Incorporated with Different Base Isolation Devices Using Pushover Analysis


  • Abhishek Sharma Kalinga University, India



Pushover analysis was started used widely in the year 1970 but it’s capability and excellent performance was identified in last 20 years. This technique is majorly used to predict the potency and glide capacity of already existing structure and shaking requisite for the same existing structure which are subjected to extremely strong earthquakes. This technique can also be employed for verifying capability newly presented structural design. Because of pushover analysis being effective it brought changes to various guidelines like ATC-40 and FEMA-356 and also some changes to design codes like Euro Code 8 and PCM 3724 in past some years. Pushover analysis is defined as an analysis in which a mathematical representation openly including the nonlinear weight bending distinctiveness of personal mechanism and fundamentals of the structure shall be subjected to monotonically rising imaginative loads representing inactivity services in a shaking until a objective dislocation is going beyond. Maximum displacement of the structure is the target displacement which is at the roof and is predictable under various selected ground motion of earthquake.
