Hybrid Simulation of Large-Scale Structures At Eth Zürich: the New 8-Actuator Multi-Axial Subassemblage Testing (Mast) Setup

Abstract eng:
In the last two decades, hybrid simulation has received increasing attention from the earthquake engineering community as a tool for simulating the nonlinear dynamic response of large structural systems in facilities with limited capacities. The quality of the simulation strongly depends of the correct application of the interface boundary conditions between the numerical and the physical subdomains. Nevertheless, the need for reducing costs and efforts related the experimental setup usually forces the partial relaxation of coupling conditions e.g., discarding interface rotational degrees-of-freedom. In this scenario, re-usable multi-axis subassemblage testing loading systems represent a convenient trade-off between achievable coupling fidelity degree and experiment cost. Along this line, this paper revisits state-of-the-art setups and presents our recent developments on this direction at the Swiss Federal Institute of Technology (ETH) in Zurich.
