The presented research studies the seismic response of a new braced steel frame type and a new design philosophy that will focus on minimizing damage to the essential structural members and ensuring satisfactory post-earthquake performance of steel buildings under service loads with minimal rehabilitation costs. The proposed frame type is composed of beams and columns with rigid connections, chevron braces and a conventional energy-dissipating member called the shear element connected between the braces and the beam. Nonlinear static pushover and seismic analyses are conducted to assess the performance of the proposed efficient energy dissipating steel frame (EEDBF) compared to the conventional concentrically braced frames (CBFs) and moment resisting frames (MRFs). The results have revealed that the EEDBF has a more stable force-lateral deformation hysteresis loop compared to CBF. The energy dissipation is comparable with NW. The story drift of the EEDBF at medium to large intensity ground motions is smaller than that of both the CBF and MRF.

Seismic Response of a Single Storey Innovative Steel Frame System
Dicleli, Murat (null; 2005-05-01)

Analytical study on seismic retrofitting of reinforced concrete buildings using steel braces with shear link
Durucan, Cengizhan; Dicleli, Murat (2010-10-01)
This paper is focused on a proposed seismic retrofitting system (PRS) configured to upgrade the performance of seismically vulnerable reinforced concrete (RC) buildings. The PRS is composed of a rectangular steel housing frame with chevron braces and a yielding shear link connected between the braces and the frame. The retrofitting system is installed within the bays of an RC building frame to enhance the stiffness, strength and ductility of the structure. The PRS and a conventional retrofitting system usin...
Seismic Retrofit of Deficient RC Structures with Internal Steel Frames
ÖZÇELİK, RAMAZAN; Akpinar, Ugur; Binici, Barış (2011-12-01)
This paper describes an experimental study on internal steel frames (ISFs) to retrofit seismically deficient reinforced concrete (RC) frames. One reference and six strengthened frame specimens were tested under constant gravity load and cyclic lateral displacement excursions. Installation of the ISF with and without anchors to the RC frame was examined. Test results showed that the snug tight ISF installed inside an RC frame may suffice to realize the benefit of implementing ISFs. If the horizontal shear st...
Numerical investigation of braces and replaceable links for steel frames
Kazemzadeh Azad, Sina; Topkaya, Cem; Department of Civil Engineering (2021-2-10)
Concentrically braced frames (CBFs) and eccentrically braced frames (EBFs) are among popular lateral load resisting systems for steel structures. The present study investigates different aspects of these systems. The part devoted to EBFs begins with a comprehensive review of research where 22 future research needs are identified and presented. This is followed by an experimental study on the low-cycle fatigue behavior of links, which are the most important members of an EBF. Results of the experimental stud...
Seismic behavior of concentrically braced frames designed to AISC341 and EC8 provisions
KAZEMZADEH AZAD, Sina; Topkaya, Cem; ASTANEH-ASL, Abolhassan (2017-06-01)
Steel concentrically braced frames (CBFs) are frequently used as efficient lateral load resisting systems to resist earthquake and wind loads. This paper focuses on high seismic applications where the brace members in CBFs dissipate energy through repeated cycles of buckling and yielding. Widely-used seismic provisions have somewhat different approaches for the seismic design of CBFs. The present study evaluates in detail the similarities and differences between the design philosophies and provisions used i...
