Analysis Of Rehabilitation Strategies For Damaged Exterior Beam-Column Connections

Abstract

This experimental study focuses on examining the behavior of exterior beam-column connections under cyclic displacement at higher frequencies. We investigate three common deficiencies—beam weak in flexure (BWF), beam weak in shear (BWS), and column weak in shear (CWS)—using specimens of varying sizes. The specimens undergo initial testing as control specimens, are then subjected to damage simulating real-world conditions, and are finally rehabilitated using two different strategies. We clearly identify each specimen type and condition through a meticulous naming convention. The study offers valuable insights into the behavior of these connections under different flaws, sizes, and repair methods, shedding light on their performance during repetitive loading and unloading cycles.
