In this paper, the seismic collapse potential of a 3-story building with large-scale MR dampers is investigated for extreme levels of ground motion beyond the MCE, where the MR dampers are controlled by various control algorithms. The control algorithms include: i) passive control; ii) linear quadratic regulator (LQR) semi-active control; iii) sliding model control (SMC) semi-active control; iv) decentralized bang-bang (DBB) semi-active control; and v) phase angle control (PAC) semi-active control. The collapse fragility curves of the building with these structural control strategies are obtained using the incremental dynamic analysis (IDA) procedure with an ensemble of ground motions recommended by FEMA P695. The nonlinear time history analysis for the IDA is conducted using OpenSees, where a phenomenological based model to account for strength deterioration in beam plastic hinge regions subject to cyclic loading is incorporated into OpenSees. The collapse fragility curves for various structural control strategies are compared and discussed to assess the performance of the building structure with MR dampers in mitigating structural collapse under extreme earthquake ground motions.
