Using shape memory alloys (SMA) bars can significantly enhance the ductility of exterior reinforced concrete joints, where they can replace the conventional steel reinforcement. This research focuses on studying the effect of using SMA on the ductility capacity of exterior reinforced concrete beam-column joints at different column axial load levels. Finite element analysis was carried out and compared with the experimental results from the literature for verification purposes, and both were compared with theoretical solutions. The results show that the use of SMA bars can improve the ductility of reinforced concrete joints noticeably, without losing load capacity. The finite element method was successful in capturing the large strain and superelastic behavior of SMA bars.

Improving seismic performance of deficient reinforced concrete columns using carbon fiber-reinforced polymers ÖZCAN, OKAN; Binici, Barış; Ozcebe, Guney (Elsevier BV, 2008-06-01) Reinforced concrete columns lacking transverse reinforcing steel do not possess necessary ductility to dissipate seismic energy during a major earthquake. The study reported herein investigates the use of carbon fiber-reinforced polymer (CFRP) wrapping as a method of retrofitting nonductile square reinforced concrete columns with low strength concrete and plain bars. Five specimens representative of transverse steel deficient flexure dominated columns in existing buildings were tested under lateral cyclic d...
Use of helical wire core truss members in space structures Işıldak, Murat; Polat, Mustafa Uğur; Department of Civil Engineering (2009) In an effort to achieve lighter and more economical space structures, a new patented steel composite member has been suggested and used in the construction of some steel roof structures. This special element has a sandwich construction composed of some strips of steel plates placed longitudinally along a helical wire core. The function of the helical core is to transfer the shear between the flange plates and increase the sectional inertia of the resulting composite member by keeping the flange plates at a ...
An analytical model for stress-strain behavior of confined concrete Binici, Barış (Elsevier BV, 2005-06-01) It is well known that the strength and ductility of concrete are highly dependent on the level of confinement provided by the lateral reinforcement. The stiffness and the constitutive behavior of the confining reinforcement (elastic, elastoplastic, etc.) are the important factors affecting the behavior of concrete. In this study, a new simple confined concrete model is developed for describing the axial and lateral deformation characteristics of concrete under triaxial compression. The stress-strain relatio...
A numerical study on response factors for steel wall-frame systems Arslan, Hakan; Topkaya, Cem; Department of Civil Engineering (2009) A numerical study has been undertaken to evaluate the response of dual systems which consist of steel plate shear walls and moment resisting frames. The primary objective of the study was to investigate the influence of elastic base shear distribution between the wall and the frame on the global system response. A total of 10 walls and 30 wall-frame systems, ranging from 3 to 15 stories, were selected for numerical assessment. These systems represent cases in which the elastic base shear resisted by the fra...
A comparative study on the nonlinear behavior of chevron and suspended zipper braced steel frames Özçelik, Ahmet Yiğit; Sarıtaş, Afşin; Department of Civil Engineering (2010) Chevron braced steel frames require large beams to redistribute the unbalanced vertical forces exerted on the beams after brace buckling. A new frame configuration similar to chevron brace was proposed in literature, where zipper columns were attached between mid-spans of the beams from second to top story. During severe ground motion, the unbalanced vertical forces caused by buckling of lower story braces are in this case redistributed to the upper story braces by these zipper columns. Consequently, all st...
