during seismic excitation that called semi-active RBS (SA-RBS). RBS is semi-active control system because it has no need to any actuator and large power supply, but just a battery-size power supply to switch the ribbed mechanism to be on or off. Nonlinear dynamic analysis of system has been carried out and performances of above RBS systems and conventional bracing system (CBS) have been investigated. Numerical results show the efficiency of CC-RBS in reducing structural damage and improving seismic energy. Also base shear is reduced when SA-RBS is used and structural damage is more uniform in this case.
