Abstract

Over the past several decades, a number of researchers have been investigating the innovative seismic materials like Magneto Rheological (MR) Smart Damper. In this research, smart damper is particularly used for Semi - Active vibration control. Many researchers have proposed smart damper device to reduce the entire structural control of vibration. Due to latest high mechanical technology, dynamic range is too large, power requirements are too low, and there is a capacity of large force with different applications to attract and also protect tall buildings, infrastructures, against very severe earthquake and wind loading. This research presents an experimental investigation of single axis shake table with 3-story frame structure and diagonally installed with magneto rheological damper to find the Maximum displacement, velocity, and acceleration. The focus of this concept is to develop a fundamental understanding of frame structures using the purpose of design and fabrication of these smart material devices in structures for natural hazard mitigation.
