Replaceable hysteretic steel dampers installed at the ends of diagonal braces offer an effective means of providing passive energy dissipation in frame‐type structures. To ensure their seismic performance, these dampers must meet both strength and deformation capacity requirements. This study presents the results of a comprehensive experimental program on welded‐plate flexural yielding dampers (WPFYDs), focusing specifically on their component‐level behavior. Design equations were developed to estimate the yield strength and initial stiffness of WPFYDs. A total of five specimens were tested to evaluate the influence of key parameters, including the number of yielding plates, plate length, plate thickness, and steel grade. The specimens were subjected to the loading protocol recommended by AISC 341 for buckling‐restrained braces. The results showed that WPFYDs can achieve yield and ultimate strengths of up to 626 kN and 891 kN, respectively, while sustaining deformation capacities greater than 40 mm without fracture. The developed equations were shown to accurately predict the observed behavior. Overall, the findings confirm that WPFYDs are not only replaceable and effective at dissipating energy but also capable of meeting the strength and deformation demands required for seismic applications.
Replaceable hysteretic dampers installed at the ends of diagonal braces provide an effective strategy to enhance the seismic resilience of concentrically braced frames (CBFs). This study investigates a newly developed rod‐connected welded‐plate flexural yielding damper (RCWPFYD) through comprehensive numerical analyses...
To enhance the seismic performance of steel archaizing buildings without altering their traditional architectural appearance, viscous dampers were installed in the Que-ti bracket regions of beam–column joints. Dynamic cyclic loading tests were conducted on four viscous damper-equipped joint specimens with single-beam a...

This study focused on the seismic performance enhancement of steel framed structures with large spans. A novel brace design, comprising a pair of brace segments connected with an angle and an effective steel curved damper, forming an A‐brace, was proposed in this study. The A‐brace was adopted in the beam‐to‐column reg...
This paper presents the results from an experimental investigation of the hysteretic behaviour of a novel‐developed class of timber‐buckling‐restrained bracings (T‐BRBs). The proposed system, which has been evaluated with and without an external steel tube, consists of a steel core and an oak mass timber casing. To eva...

Cylindrical shell structures, such as wind turbine towers, are continuously growing in size, and their structural performance is becoming increasingly governed by buckling. Under the critical loading scenario of combined uniform bending and torsion, these shells develop destabilising compressive meridional stresses tog...

Steel–timber composite structures offer a sustainable alternative to conventional beams by combining the high strength of steel with the circularity and workability of timber. When paired with demountable shear connectors, the system activates composite action and enables full reusability of each component, further enh...
