A numerical and analytical study on distortional buckling of doubly-symmetric steel I-beams
Kalkan, Ilker; Buyukkaragoz, Alper (Elsevier Sci Ltd, 2012)This study investigates the effect of web distortions in a lateral distortional buckling mode on the buckling moments of doubly-symmetric steel I-beams. Analytical buckling moment expressions applicable to both elastic and ... -
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 ... -
Restrained shrinkage cracking of self-consolidating concrete roads
Akgungor, Ali Payidar; Sevim, Ozer; Kalkan, Ilker; Demir, Ilhami (Walter De Gruyter Gmbh, 2018)The present study is dedicated to investigate the liability of continuously reinforced concrete pavement (CRCP) cast with self-consolidating concrete (SCC) to restrained shrinkage cracking and the values of restraint ... -
Rollover instability of precast girders subjected to wind load
Lee, Jong-Han; Kalkan, Ilker; Lee, Jong-Jae; Cheung, Jin-Hwan (Ice Publishing, 2017)The use of longer and deeper precast concrete girders has created concern regarding their rollover instability, particularly during construction. Current design and construction specifications do not provide any specific ... -
Seismic performance of R/C structures under vertical ground motion
Bas, Selcuk; Lee, Jong-Han; Sevinc, Mukadder; Kalkan, Ilker (Techno-Press, 2017)The effects of the vertical component of a ground motion on the earthquake performances of semi-ductile high-rise R/C structures were investigated in the present study. Linear and non-linear time-history analyses were ... -
Strengthening and Repair of Reinforced Concrete Beams Using External Steel Plates
Aykac, Sabahattin; Kalkan, Ilker; Aykac, Bengi; Karahan, Servet; Kayar, Sinan (Asce-Amer Soc Civil Engineers, 2013)The study presents the results of an experimental program aimed at investigating the flexural behavior of externally plated RC beams. 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 RC T-beams with perforated steel plates
Aykac, Sabahattin; Kalkan, Ilker; Aykac, Bengi; Ozbek, Eray (Ice Publishing, 2013)The study investigates the flexural behaviour and ductilities of reinforced concrete (RC) T-beams strengthened with perforated steel plates. A total of eight full-scale RC T-beams were tested. Three strengthened beams and ... -
Strengthening of reinforced concrete beams with epoxy-bonded perforated steel plates
Aykac, Sabahattin; Kalkan, Ilker; Uysal, Ali (Techno-Press, 2012)Although being one of the most popular strengthening techniques in reinforced concrete beams, the use of steel plates bonded to the soffit raises problems of ductility. This study aims at investigating the influence of the ...
