Characterization and Implementation of Hysteretic Device in Steel Structure

Abstract

Earthquakes happen all around the world. Many types of structures rely on their postelastic nature to survive through significant ground motion. The capacity of the frame system to dissipate energy quickly while enduring massive inelastic deformation is critical for survival in severe earthquakes. Appropriate design techniques that allow robust and dependable hysteretic energy-dissipation processes were used to produce this ductile response and avoid brittle breakdowns. As a result, the present situation for safeguarding steel structures from earthquake loading is shifting away from elastic deformation and toward inelastic deformation in order to eliminate the energy of severe seismic loading. To explain cyclic behavior, the current work uses numerical and experimental methods to characterize an ADAS type metallic yield damper. It was discovered that the response of a metallic damper is determined by its geometry and mechanical properties. For experimental work, the ADAS type metallic yield damper is used. The yield displacement of the system is determined using SAP2000’s pushover analysis for damper design. The proposed damper is then studied in ABAQUS FEM software under sinusoidal load and different Earthquake ground motion, as well as through a Python program created for the Bouc-wen Model, which provides restoring force. The outcomes of the ABAQUS and Python programs are compared. The introduction of a design damper to the 9-story benchmark building is also covered in this study.
