DOI: 10.1007/s10518-017-0116-8
Abstract: Abstract This paper quantifies the impact of the non-stationary content (time-varying parameters that are not captured by power spectral content alone) of different ground-motion types (near/far field, with/without pulses time-series) on the nonlinear dynamic response… read more here.

DOI: 10.1007/s10652-017-9529-9
Abstract: Scour is defined as the processes of removal of sediment particles from water stream bed by the erosive action of activated water, and also carries sediment away from the hydraulic structures. Scour is the main… read more here.

DOI: 10.1007/s42241-019-0017-1
Abstract: The presence of bridge piers in natural rivers significantly changes the flow and boundary conditions. As a consequence, ice jams can often be initiated in front of bridge piers. With the changes in flow conditions,… read more here.

DOI: 10.1016/j.soildyn.2019.105955
Abstract: Abstract Safety of a foundation under seismic loading is strongly dependent on the inertial forces transmitted by the superstructure, exchanged with the surrounding soil and acting into the foundation itself. The latter contribution, typically neglected… read more here.
