Real-time hybrid simulation (RTHS) is a state-of-the-art, accurate, affordable method for simulating seismic effects on structures with loading rate-dependent behaviour. In RTHS, a part of the system that cannot be accurately modelled numerically is simulated experimentally in the laboratory, and the rest numerically. The response of the hybrid system is obtained in real-time by solving the governing equations of motion. This communication demonstrates an implementation of RTHS in the Pseudo Dynamic Testing Facility at IIT Kanpur and its application to seismic response simulation of a two-storey reinforced concrete special moment-resisting frame building with in-house-built nonlinear viscoelastic dampers.

In RTHS, a part of the system that cannot be accurately modelled numerically is simulated experimentally in the laboratory, and the rest numerically. The response of the hybrid system is obtained in real-time by solving the governing equations of motion. This communication demonstrates an implementation of RTHS in the Pseudo Dynamic Testing Facility at IIT Kanpur and its application to seismic response simulation of a two-storey reinforced concrete special moment-resisting frame building with in-house-built nonlinear viscoelastic dampers.
