Effectiveness of base-isolated low-rise masonry building under excitation from earthquakes
Magazine of Civil Engineering, 2021 Low-rise masonry building is one of the most commonly adopted structural types even in earthquake prone regions in developing countries. The building is generally susceptible to damage due to earthquake induced motion and may suffer partial or total ...

Soil–Structure Interaction Consideration for Base Isolated Structures under Earthquake Excitation
Buildings, 2023 This study aims to analytically implement base isolation with soil–structure interaction (SSI) on a sample structure and to develop a very simple solution to add these combined effects into the mass, damping and stiffness matrices of the structure.
