Mechanical properties and displacement capacity of welded-plate flexural yielding dampers Dursun, Süleyman Eren; Topkaya, Cem; BOZKURT, MEHMET BAKIR (2026-01-01) Replaceable hysteretic steel dampers can be installed at the ends of diagonal braces to provide passive energy dissipation in frame-type structures. These dampers must satisfy both strength and displacement requirements. P...
Experimental and numerical investigation of steel-concrete composite beams with demountable bolted angle shear connectors Karakuş, Berk; Arıkoğlu, Pınar; Topkaya, Cem (2025-10-15) Demountable bolted angle shear connectors have been developed for use in composite beams to promote more sustainable construction practices. Their performance was evaluated through horizontal pushout tests to determine the...
Behavior of overlap core steel encased BRBs with different end connections Balıkçı, Elif Müge; BOZKURT, MEHMET BAKIR; Topkaya, Cem (2025-08-01) This paper presents findings from an experimental program aimed at investigating the behavior of full-scale overlapped core steel-encased buckling-restrained braces (OCSE-BRBs) with different end connections. The primary v...
Seismic behavior of cold-formed steel framed multi-panel and two-story shear walls Pehlivan, Barış Mert; Baran, Eray; Topkaya, Cem (2025-01-01) This paper presents an experimental investigation on the seismic behavior of cold-formed steel (CFS) shear wall systems. Two sets of cyclic lateral loading tests were conducted on OSB sheathed CFS shear wall specimens. The...
Pushout tests on demountable bolted angle shear connectors for steel-concrete composite structures Karakuş, Berk; Arıkoğlu, Pınar; Topkaya, Cem (2024-10-15) Welded connectors are commonly utilized in steel-concrete composite construction. However, these connectors lack demountability, hindering the recycling or reuse of steel sections. In response to this limitation, high-stre...
Stiffening of I-section MRF beams against degradation due to local buckling Karagümüş, Anıl; Topkaya, Cem (2024-02-01) Moment resisting frame (MRF) beams under cyclic loading are vulnerable to local flange and web buckling. The Seismic Provisions for Structural Steel Buildings (AISC341) prescribe width-to-thickness ratio limits, which are ...
Numerical Analysis of Stiffness Requirements For Wind Girders In Open-Top Cylindrical Steel Tanks ZEYBEK, ÖZER; Topkaya, Cem (2023-10-20)
FEMA P695 seismic performance evaluation of Cold-formed steel buildings with different shear wall strengths and stiffnesses Pehlivan, Baris Mert; Baran, Eray; Topkaya, Cem (2023-10-01) Lateral load capacity and stiffness of CFS framed OSB sheathed shear walls can be improved by increasing the number of fasteners between sheathing panel and framing members or by providing sheathing on both sides of panel....
8-MW wind turbine tower computational shell buckling benchmark. Part 1: An international ‘round-robin’ exercise Sadowski, Adam J.; et. al. (2023-06-01) An assessment of the elastic-plastic buckling limit state for multi-strake wind turbine support towers poses a particular challenge for the modern finite element analyst, who must competently navigate numerous modelling ch...
Development of H-shaped hysteretic dampers for steel concentrically braced frames Dursun, Süleyman Eren; Topkaya, Cem (2023-03-01) A new type of hysteretic damper, which can easily be mounted at the ends of I-section braces in concentrically braced frames (CBFs), is proposed in this paper. The main goal is to develop a damper which would enable the I-...
