The plastic and the ultimate resistance of four-bolt extended end-plate connections
Özkılıç, Yasin Onuralp; Topkaya, Cem (2021-06-01)
© 2021Widely used design guidelines and specifications provide methods to calculate plastic resistance of end-plates considering yield line mechanisms. Experiments reported to date showed that the ultimate resistance of en...
Experimental and numerical analysis of cold-formed steel floor trusses with concrete filled compression chord
GÜLDÜR, HAZAL; Baran, Eray; Topkaya, Cem (2021-05-01)
© 2021 Elsevier LtdFloor trusses fabricated from cold-formed steel (CFS) sections offer several advantages over more conventional floor systems. The current paper reports the findings of an integrated experimental and nume...
Seismic performance of eccentrically braced frames designed to AISC341 and EC8 specifications
Aied Qissab Al-Janabi, Musab; Topkaya, Cem (2021-02-01)
© 2020 Institution of Structural EngineersIn the United States, steel eccentrically braced frames (EBFs) are designed according to AISC341 Specification while in Europe EC8 provisions are used. The European provisions were...
Performance comparison of BRBFs designed using different response modification factors
Güner, Tuğberk; Topkaya, Cem (Elsevier BV, 2020-12-15)
This paper presents details of the numerical examination and performance comparison of steel buckling restrained braced frames (BRBFs) designed with different response modification factors, using the next-generation perfor...
Behavior of channel connectors in steel-concrete composite beams with precast slabs
Arıkoğlu, Pınar; Baran, Eray; Topkaya, Cem (Elsevier BV, 2020-09-01)
The use of precast decks in steel-concrete composite construction offers variety of advantages. Research to date has mostly focused on the use of headed stud connectors with hollow core precast decks for building structure...
The response of tall buildings to far-field earthquakes and the case of a 49-storey steel building
Muin, Sifat; Astaneh-Asl, Abolhassan; Topkaya, Cem (2020-06-01)
This paper investigates the seismic response of an instrumented 49-storey steel structure in San Francisco to weak, far-field, and strong, near-field ground motions. The instrumentation records obtained during the 1989 Lom...
An energy dissipating hold down device for cold-formed steel structures
Pehlivan, Barış Mert; Baran, Eray; Topkaya, Cem (Elsevier BV, 2020-03-01)
A two-phase experimental investigation has been conducted for the development and evaluation of a hold down device that has energy dissipating feature. Focus of the first phase was the development of the device itself, whi...
Nonsymmetrical loading protocols for shear links in eccentrically braced frames
Al-Janabi, Musab Aied Qissab; Topkaya, Cem (Wiley, 2020-01-01)
The AISC Seismic Provisions for Structural Steel Buildings (AISC 341-16) provide a testing protocol for qualification of link-to-column connections in eccentrically braced frames (EBFs). This symmetrical testing protocol w...
Stress resultants for wind girders in open-top cylindrical steel tanks
Zeybek, Ozer; Topkaya, Cem; Rotter, J. Michael (Elsevier BV, 2019-10-01)
Empty open-top cylindrical steel tanks are susceptible to buckling when subjected to external pressure due to wind or partial vacuum due to blocked vents. A "wind girder" is commonly used at the top of the tank wall to inc...
Effect of Support Width on Stress Resultants in Ring Beams Interacting with Silo Shells
Topkaya, Cem; Zeybek, Özer (2019-09-20)
Elevated cylindrical metal silos are often supported on a ring beam which rests on discrete column supports. The ring beam plays an important role in redistributing the majority of the discrete forces from the column suppo...
