Behavior and strength of hidden Rc beams embedded in slabs
Ozbek, Eray; Aykac, Bengi; Bocek, Meryem; Yilmaz, Mahmut Cem; Mohammed, A. B. Khadeeja; Er, Sule Bakirci; Aykac, Sabahattin (ELSEVIER, 2020)Reinforced concrete (RC) beams protrude from the ceiling, unless there is an infill wall beneath. Sometimes the construction of these beams is avoided due to aesthetic concerns, and instead a reinforcement arrangement with ... -
Behavior of Postfabricated RC Beams under Monotonic Transverse Loading
Aykac, Sabahattin; Jamal, Rohullah; Ozbek, Eray; Kalkan, Ilker; Aykac, Bengi (Asce-Amer Soc Civil Engineers, 2019)Postfabricated beams, that is, newly constructed beams in an existing structural system, provide an effective remedial solution to the serviceability and strength problems in an existing floor system and the discontinuities ... -
Behaviour of brick infill walls strengthened with expanded steel plates
Cumhur, Alper; Altundal, Adil; Kalkan, Ilker; Aykac, Sabahattin (Springer, 2016)The present study was dedicated to investigate an effective, economical and convenient method for strengthening brick infill walls, i.e. the use of externally-bonded expanded steel plates. A total of 30 plastered wall ... -
Behaviour Of Reinforced Concrete Weak Column-Beam Connections
Bakirci Er, Sule; Aykac, Sabahattin; Can, Husnu (Gazi Univ, Fac Engineering Architecture, 2014)In this study the behavior of RC weak column-beam connections which have no joint stirrups and lack of column stirrups, are investigated experimentally under earthquake loads. Edge beam to column joints were tested under ... -
Discussion on "Seismic capacity of masonry infilled RC frame strengthening with expanded metal ferrocement" by A. Leeanansaksiri, P. Panyakapo, A. Ruangrassamee [Eng. Struct. 159 (2018) 110-127]
Aykac, Sabahattin; Ozbek, Eray; Kalkan, Ilker; Aykac, Bengi (Elsevier Sci Ltd, 2018)A discussion on the paper by Leeanansaksiri et al. (2018) is presented. In the paper, strengthening of the masonry infill walls using ferrocement reinforced with standard expanded steel plates (EMS) was investigated ... -
Flexural Behavior and Strength of Reinforced Concrete Beams with Multiple Transverse Openings
Aykac, Bengi; Aykac, Sabahattin; Kalkan, Ilker; Dundar, Berk; Can, Husnu (Amer Concrete Inst, 2014)Reported are the results of experiments on 10 rectangular reinforced concrete (RC) beams with and without multiple web openings. The effects of opening geometry, the-use of longitudinal stirrups in the posts between the ... -
Flexural behavior of RC beams with regular square or circular web openings
Aykac, Bengi; Kalkan, Ilker; Aykac, Sabahattin; Egriboz, Yusuf Emre (Elsevier Sci Ltd, 2013)This paper presents a study aimed at investigating the influence of multiple web openings along the length of an RC beam on its flexural behavior. A total of nine rectangular beams were tested. Diagonal reinforcement around ... -
Flexural strengthening and repair of RC slabs by adding a new RC layer
Aykac, Sabahattin; Kalkan, Ilker; Tankut, Tugrul (Ernst & Sohn, 2016)The present paper summarizes the findings of an experimental programme to investigate a strengthening/repair technique through the introduction of a new RC layer to an existing slab. Six RC slabs, composed of twelve ... -
Lateral stability of reinforced-concrete beams with initial imperfections
Kalkan, Ilker; Bocek, Meryem; Aykac, Sabahattin (Ice Publishing, 2016)The paper presents the results of an analytical study aimed at investigating the lateral stability of reinforced-concrete (RC) beams with initial geometric imperfections. Based on the experimental results in the literature, ... -
New Experimental Setup for Seismic Testing of Exterior RC Beam-Column Joints
Aykac, Sabahattin; Kalkan, Ilker (Amer Soc Testing Materials, 2015)Exterior beam-column joints are commonly tested to investigate the influence of different strengthening and repair techniques on the seismic performances of RC structures. All of the internal forces developing at the ends ... -
Recommendations for calculation of strengthened brick walls with perforated plates
Ozbek, Eray; Aykac, Bengi; Can, Husnu; Kalkan, Ilker; Aykac, Sabahattin (Gazi Univ, Fac Engineering Architecture, 2019)There are many studies relating to the strengthening of infill brick walls, which contribute partially to the resistance against the seismic forces, by using different methods and materials to make them behave similarly ... -
Strengthening and Repair of Reinforced Concrete Beams Using External Steel Plates

A total of 13 full-scale rectangular RC beams were tested. The effects on the behavior ... -
Strengthening of hollow brick infill walls with perforated steel plates
Aykac, Sabahattin; Kalkan, Ilker; Seydanlioglu, Mahmut (Techno-Press, 2014)The infill walls, whose contribution to the earthquake resistance of a structure is generally ignored due to their limited lateral rigidities, constitute a part of the lateral load bearing system of an RC frame structure. ... -
Strengthening Of Plastered Hollow Brick Infill Walls Using Strip Concrete/Reinforced Concrete Panels
Baran, Mehmet; Aktas, Merve; Aykac, Sabahattin (Gazi Univ, Fac Engineering Architecture, 2014)In Turkey, majority of the building stock is known to be inadequate against earthquake and is required to be strengthened. Cast-in-place reinforced concrete (RC) infill walls, connected to the frame systems by use of epoxy ... -
