In the present study, the seismic vulnerability of a hybrid mold transformer was investigated using a dynamic analytical approach incorporating the experimental results of shaking table tests. The analytical model consisted of linear springs and plastic beam elements, and it has six degrees of freedom simulating the hybrid mold transformer. The dynamic characteristics of the analytical model were determined based on the shaking table tests. The reliability of the analytical model was verified by comparing the test results and analytical results. In order to assess the seismic vulnerability, three critical damage states observed during the shaking table tests were investigated by incorporating the three performance levels specified in ASCE 41-17. Comprehensive dynamic analyses were performed with a set of twenty earthquakes in consideration of the variation of the uncertain parameters (such as the effective stiffness and coil mass) of the mold transformer. Based on the analytical results, fragility curves were established to predict the specified exceedance probability of the mold transformer according to the performance levels.

An innovative dissipative (INERD Pin) connection system, which was previously developed for seismic resistant X-braced steel frames, was applied to retrofit existing precast industrial buildings designed only for gravity loads. Nonlinear dynamic analyses were carried out and the effectiveness of the dissipative connection system was evaluated. The INERD Pin connection system increased both the deformation capacity and the stiffness of the buildings, reducing damage of the structural elements. In case of low seismic actions, the INERD Pin connection system especially enhanced the stiffness of the structure, causing only small reductions of column rotations and top displacements. In case of severe seismic actions, the addition of the dissipative connections showed all its effectiveness particularly for low rotation capacity at column base, increasing the energy dissipation capacity and reducing the displacements of the structure. The results of the numerical investigations demonstrated the possibility to reduce the seismic vulnerability of existing precast buildings by means of dissipative connection systems.
