Evaluation of the seismic performance of isolated electrical transformers under pulse-like excitations [PDF]
Numerical Methods in Civil Engineering, 2022 Damage sustained by electrical transformers in past strong earthquakes led to irrecoverable and severe economic losses. The seismic performance evaluation is associated with the loss of proper functioning of transformers.

Seismic Performance of Simple Slopes
Soils and Foundations, 1995 ABSTRACT This paper is concerned with an extension of a rotational limit equilibrium method for determining the permanent displacements of slopes under seismic excitation. In the proposed procedure, the sliding mass is treated as a rigid rotating body defined by a log spiral trace.
