Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

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.

Evaluation of Seismic Response of 3D Building Frame with and without Base Isolation Using Finite Element Analysis

Engineering Proceedings, 2023
An earthquake is a force which is unpredictable and can cause serious damage to a structure and its structural components. For improved safety, the seismic design of the building should be adequate, and measures should be taken for vibration control.
