Cold-formed steel (CFS) structural systems are considered to be an innovative and newly developing construction method. Because of advantages such as lower fabrication periods, high strength/weight ratio and ease of construction, CFS structural systems have been used increasingly all around the world, including seismically active areas. Although there have been many studies in the literature, CFS structural systems are relatively new for the civil engineering practice and few existing specifications regarding the subject still lack necessary detailing for safe and economical design and construction of these systems. As a result, there is a major concern regarding the performance of CFS structural systems especially under seismic actions. The current study aims at improving the understanding of the structural behavior of a specific type of CFS building system, where the lateral load resisting system is made of shear walls sheathed with oriented strand board (OSB) panels. An extensive and detailed experimental investigation on various components of a typical sheathed CFS shear wall system, as well as the connections between these components was conducted in this study. Experimental program consisted of several stages and various components of a lateral load resisting CFS system. Load testing of hold down devices, investigation of different sheathing and fastener configurations for shear walls, tests on shear wall groups where wall panels are placed both horizontally and vertically and investigation of various connection details between wall panels, as well as experiments on three dimensional structural assemblies utilizing CFS shear walls and a floor system were included in the study. In addition to the extensive experimental part, a numerical study was also included in the thesis work. By using the experimental findings and load-displacement behavior data obtained from CFS shear walls, both single wall panels and full-scale buildings were modeled and analyzed. It was aimed to investigate the seismic response of CFS framed archetype buildings utilizing OSB sheathed wall panels with different levels of stiffness and shear resistance. Nonlinear time history analyses were conducted on archetype buildings and collapse performance evaluation was performed according to FEMA P695 methodology.

Seismic behavior of semi-precast concrete shear walls
Golnesa Karimi, Zindashti; Binici, Barış; Canbay, Erdem (null; 2017-10-11)
Successful seismic performance of well-designed and constructed precast concrete members is crucial for sustainable, economical and high speed construction. The main disadvantage of precast concrete is the difficulty of detailing the connection region between the vertical and horizontal load bearing elements to ensure structural integrity. Double wall system, being a semi-precast approach, consists of two precast reinforced concrete layers encasing a cast-in-place concrete layer which is usually employed to...
Numerical modeling of cold-formed steel sheathed shear walls under lateral loading
Topçuoğlugil , Yağmur; Baran, Eray; Department of Civil Engineering (2019)
Cold-formed steel (CFS) structural systems have been used increasingly in seismically active regions. Shear walls consisting of CFS framing and sheathing panels constitute one type of lateral force resisting system for such CFS framed buildings. The purpose of this study is to develop an efficient numerical model to predict the lateral load response of shear walls that are framed with CFS profiles and sheathed with oriented strand board (OSB) panels. Numerical modeling of shear walls was conducted in OpenSe...
Scale Effect on CFRP Strengthening of Infilled Reinforced Concrete Frames
AKIN, EMRE; Canbay, Erdem; Binici, Barış; Ozcebe, Guney (2015-06-01)
The diagonal application of Carbon Fiber-Reinforced Polymer fabrics on hollow clay tile infill walls has been qualified as an efficient rehabilitation method for deficient reinforced concrete frames. However, majority of the experimental studies were conducted on 1/3-scaled RC frames and the effect of specimen scaling has not been questioned. In the current study, the results of an experimental campaign on 1/2-scaled RC frames are presented. Test specimens are grouped in two series having two different aspe...
Experimental and numerical investigation of cfs-concrete composite trusses
Güldür, Hazal; Baran, Eray; Department of Civil Engineering (2018)
Cold-formed steel (CFS) structural systems have been intensely studied especially due to the economy and ease of implementation that they provide. A common failure mode of CFS members is the local instability of the section. The aim of this study is to control the local instability in CFS floor trusses by providing concrete infill inside compression chord members. Numerical and experimental studies were conducted in order to investigate the flexural behavior of steel-concrete composite trusses made of CFS s...
Seismic Strengthening with Precast Concrete Panels - Theoretical Approach
Baran, Mehmet; Canbay, Erdem; Tankut, Tugrul (2010-01-01)
An economical, structurally effective and practically applicable seismic retrofitting technique has been developed on the basis of the principle of strengthening the existing hollow brick infill walls by using high strength precast concrete panels. The technique would not require evacuation of the building and would be applicable without causing much disturbance to the occupant. For this purpose, a total of eighteen reinforced concrete frames with hollow brick infill walls were tested under reversed cyclic ...
