WebDec 7, 2024 · The recorded history of self-centering structures goes as far back as the Bronze Age (3000–1000 BC), when ancient builders were designing structures mainly supported by free-standing columns in the ancient Egyptian and Minoan civilizations ( … WebFeb 1, 2024 · First, the paper demonstrates the relationship between each of these target parameters with the levels of the self-centering to steel reinforcement ratio, aspect ratio, and axial load ratio (ALR) in 72 innovative and conventional RC shear walls.
WebSep 1, 2024 · The self-centering concrete wall is subjected to lateral cyclic loading, and the openings and closing of gap occurs at the wall and foundation beam. Therefore the surface to surface contact elements are adopted to model such behavior. The tangential contact behavior between the master and slave surface is modelled by tangential friction. WebNov 11, 2007 · Lateral displacements eventually result in a separation gap forming only at the wall-foundation beam connection. The gap reduces the wall stiffness and results in nonlinear response. Design of these walls is made with the explicit objective of ensuring a self-centering response.
