Studies on Modeling and Control of RCC Frame with MR Damper

Magnetorheological Dampers (MR) have the ability to mitigate seismic hazards caused to a structure by reducing its potential to undergo large displacements. The objective of the paper is to formulate an analytical modeling technique to perform the hybrid simulation. The seismic response of a single-story frame employed with an MR damper is analyzed for hybrid simulation. The paper compares the results of several parameters subjected to specific earthquake ground accelerations using an object-oriented programming software called OpenSees. A program source code developed by OpenSees is run with Active Tcl script and changes are made for specific models to validate the simulations for each model. The time-series data for ground accelerations of the earthquakes considered in the models (El Centro, Kobe, and Northridge earthquakes) is taken as an input to perform a simulation. OpenSees software is present as an executable file that runs this source code of the program, performs the simulation for each of the models, and saves the output. The simulated models give us several outputs like acceleration, displacement, damper force, etc., simultaneously after the program is run. The results of the output are deliberated in the form of graphs.
