PhD Thesis at the University of Basrah Examines the Behavior of Partially Isolated Buildings
A PhD thesis at the College of Engineering at the University of Basrah examined the behavior of partially isolated buildings equipped with floor-level dampers subjected to seismic loads.
The thesis, presented by student Ali Abdul-Rahim Abdullah, aimed to evaluate the efficiency of combining partial base isolation using lead rubber bearings (LRBs) with viscous dampers to improve structural performance while reducing construction costs compared to full base isolation.
The thesis included five chapters, during which the student discussed the development of several numerical models for regular and irregular buildings in ETABS V22. These models incorporate various isolation configurations, including full base isolation, partial isolation at the central, middle, and perimeter columns, and floor-level isolation on different floors.
