Abstract
Researches in past reviewed for base isolation analysis using response spectrum it is found that the design in ancient time are not sure and safe due to lake of technology and lesser software analysis availabilities. Some countries applied base isolation these days and the building response constructed with base isolation performed better at practical ground. The response of base isolated building is lesser in terms of amplitude and the cost of the building can also be optimized. Many researchers studied for this subject and they concluded that base isolation must be applied in critical seismic zones and the isolators must be used to save lives and properties. It is seen that Indian construction practices are lacking to apply use of base isolation in building design. It is suggested in the end that it must be motivated to study and research base isolation in Indian constrains and conditions.
Highlights
In mechanical engineering systems, to control the vibration, Tuned mass dampers are used
In order to minimize the vibrations of high storey building and engineering structures, Tuned Mass Dampers are widely adopted
The structure was once again analyzed by keeping TMD on top of the building using dynamic analysis and the time period, displacement at the locations to illustrate the utility of the study, the comparison of the resultants are done without Tuned Mass Damper
Summary
To control the vibration, Tuned mass dampers are used. In order to minimize the vibrations of high storey building and engineering structures, Tuned Mass Dampers are widely adopted. Structural vibration control applications such as dynamic absorbers and Tuned Mass Dampers are of Tuned absorbers and Tuned dampers. As in increasing of damping ratio causes a reduction in the stress and acceleration. In case of earthquakes to control displacements, accelerations and internal stress can be done by tuned mass damper. There are different types of methods of control for large modern structures This system is usually used to reduce vibration occurred by the wind and traffic like pedestrians/railway trains .Some vibrations may be acceptable for structures like slender bridges, stacks, high, and slender buildings has low levels of damping. A multistory building is assembled with a Tuned Mass System on the top of the roof
