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 this gap through an integrated experimental and numerical study on lateral load response of double side sheathed CFS-framed wall panels utilizing relatively small fastener spacing. The experimental investigation included cyclic tests on nine 1220x2440 mm wall panels. For the tested walls the predominant failure mode was buckling of boundary studs. The average maximum drift ratios of all tests were 3.2% and 3.0% in two loading directions. The corresponding average drift ratios at peak load capacity were 2.9% and 2.7%. The numerical part of the study included detailed modeling of wall panels using the OpenSees platform following the fastener-based and equivalent brace modeling approaches. In the fastener-based models, the nonlinear behavior of each screw between the CFS framing members and the sheathing panel was simulated by a nonlinear spring element. Material models used for these nonlinear spring elements were calibrated with the data from physical testing of connection screws. In the equivalent brace model, inelastic response of all connection screws was lumped into two nonlinear brace elements. Material models used for these brace elements were calibrated with the measured lateral load-drift data from wall panel testing. Good agreement was obtained between the numerical responses from both modeling approaches and the measured response.

Experimental investigation of structural systems made of sheathed cold-formed steel wall panels Pehlivan, Barış Mert; Baran, Eray; Department of Civil Engineering (2023-1-12) 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 regardi...
EVALUATION OF DISPLACEMENT AMPLIFICATION FACTORS FOR STEEL BUCKLING RESTRAINED BRACED FRAMES Bozkurt, Mehmet Bakir; Ozkilic, Yasin Onuralp; Topkaya, Cem (2016-12-09) In the United States, design of buckling restrained braced frames (BRBFs) is conducted using the recommendations given in the Seismic Provisions for Structural Steel Buildings (AISC341-10) and Minimum Design Loads for Buildings and Other Structures (ASCE 7-10). In this study, deflection amplification factor given in ASCE7-10 for BRBFs was evaluated. Pursuant to this goal. three archetypes composed of single diagonal BRBFs were designed. The archetypes represent designs in high seismic regions which are defi...
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...
Behavior of cold-formed steel wall panels under monotonic horizontal loading Baran, Eray (2012-12-01) This paper summarizes the findings of an experimental study on cold-formed steel (CFS) wall panels with oriented strand board (OSB) sheathing. Static lateral load tests were conducted on a total of thirteen full-scale wall panel specimens to investigate the performance of CFS walls utilizing primarily the construction details used in Turkey. Experimental results revealed that the geometry of hold-down attachment used at the base of CFS wall panels to transfer tensile forces has a major effect on the overall...
Cyclic Testing of Reinforced Concrete Double Walls ALDEMİR, ALPER; Binici, Barış; Canbay, Erdem (2017-03-01) Reinforced concrete double walls are semi-precast structural elements constructed with factory-produced concrete shells on two exterior sides and cast-in-place concrete in the middle of the section. Their use has been limited in seismic zones due to the difficulty of connecting the adjacent double walls for monolithic action, and providing suitable seismic details in the presence of the lattice girder that is used to hold the concrete shells together. These limitations were overcome with the invention of di...
