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 ...
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-...
Investigation of CFS shear walls with two-sided sheathing and dense fastener layout
Pehlivan, Barış Mert; Baran, Eray; Topkaya, Cem; Isik, Yagmur Topcuoglugil (2022-11-01)
Even though CFS framed shear walls have been the subject of many research, test data on walls sheathed with OSB panels on both sides using relatively small fastener spacing is scarce. The current investigation aims to fill...
An Experimental and Analytical Study on Cold Formed Steel Floor Trusses with Bare and Concrete Filled Compression Chords
Dizdar, Çağan; GÜLDÜR, HAZAL; Baran, Eray; Topkaya, Cem (2022-10-17)
Stiffness requirements for wind girders in open-top cylindrical steel tanks
Zeybek, Özer; Topkaya, Cem (2022-07-01)
© 2022 Elsevier LtdAboveground cylindrical storage tanks are very thin shell structures which are prone to buckling when subjected to wind pressure. Both external and internal pressures are developed due to wind action, an...
Development of a loading protocol for long links in eccentrically braced frames
Al-Janabi, Musab Aied Qissab; Balıkçı, Elif Müge; Topkaya, Cem (2022-06-01)
© 2022 Elsevier LtdLoading protocols are generally used for qualification testing of structural members. In eccentrically braced frames (EBFs), the connections of short links attached to columns are evaluated based on the ...
Seismic performance evaluation of eccentrically braced frames with long links using FEMA P695 methodology
Balıkçı, Elif Müge; Al-Janabi, Musab Aied Qissab; Topkaya, Cem (2022-05-01)
© 2022 Elsevier LtdShort links that primarily yield under shear are usually preferred in eccentrically braced frames (EBFs) due to their high rotation and energy dissipation capacities. Long links that yield under flexure ...
Stability of laterally unsupported shear links in eccentrically braced frames
Özkılıç, Yasin Onuralp ; Zeybek, Ozer; Topkaya, Cem (2021-12-01)
I-shaped links in eccentrically braced frames (EBFs) are susceptible to lateral or lateral torsional buckling when subjected to cyclic link rotations. Lateral bracing should be provided at the ends of the I-shaped links in...
