“…For the second line of bolts, only this method gives similar results to the FE analysis. Very similar experimental and finite element results were also gained by other researchers dealing with the pretensioned bolted endplate connections [9], [13], [16] to [21] Based on the results it can be concluded that the analytical method presented in this paper is the most accurate. Nevertheless these results do deviate slightly from the FE analysis but these deviations are acceptable.…”

“…They reported that the rotation capacities of the test specimens satisfied the ductility design requirements of earthquake‐resistance for most seismic regions. Saberi et al () investigated the behavior of bolted connections as a function of the thicknesses of the end plate and T‐stub flange using a numerical method. In their results, they pointed out that the performance of bolted T‐stub connections is more sensitive to component thickness than end plate connections Muresan and Balc () demonstrated experimental results where increased displacement occurred around the tension flange of the connection.…”

Summary This paper proposes dry mechanical beam–column joints for fully restrained moment connections of concrete components. This novel joint can be used for reinforced concrete precast frames and steel–concrete composite precast frames. The new dry mechanical joint consists of extended steel plates with bolts designed to transfer tension and compression forces, providing fully restrained moment connections at the beam–column joint. The extended end plate with bolts introduced for column‐beam joint assembly was originally used in the steel moment frame, as introduced in AISC 358. This study developed similar but unique mechanical joint details for concrete frames in order to provide fully restrained moment connections for both steel–concrete composite precast frames and reinforced concrete precast frames. Experimental and analytical investigations were performed to verify the structural behavior of fully restrained moment connections for concrete components in order to identify the parameters that influence the structural behavior of dry mechanical moment concrete connections. These connections are expected to be used in modular offsite construction for buildings and heavy industrial plants. Copyright © 2016 John Wiley & Sons, Ltd.

“…Yapılan çalışma sonucunda, T kesit levhalı birleşimlerin levha kalınlığı değişimine daha hassas oldukları görülmüştür. Her iki birleşim türünde de levha kalınlığının azalmasıyla, maksimum momente daha yüksek dönme değerlerinde ulaşıldığı görülmüştür [14]. Shaker ve Abd Elrahman alın levhalı birleşimlerde alın levhası kalınlığı, bulon çapı, kolonda süreklilik levhası olup olmaması değişimlerini incelemek için [1]'de verilen modellemelerden faydalanmışlardır [15].…”

ÖZETBu çalışma, monotonik yükleme altında sonlu elemanlar analizleri gerçekleştirilen alın levhalı bulonlu birleşimlerde, alın levhası kalınlığı değişimi ile panel bölgesi güçlendirmesinin etkisini incelemektedir. Çalışmanın ilk aşamasında, literatürden alınan iki adet alın levhalı bulonlu birleşimin sonlu elemanlar analizi yapılmış ve literatürdeki sonuçları ile bu çalışmadaki sonuçları karşılaştırılmıştır. İkinci aşamada ise, literatürden alınan bu birleşimlerdeki alın levhası kalınlığının arttırılmasının ve panel bölgelerinin güçlendirilmesinin etkileri incelenmiştir. Panel bölgesini güçlendirmek için diyagonal koyulmuş levha veya kolon gövdesi takviye levhası kullanılmıştır. Birleşimlerdeki bulonlar öngerilmeli olup, analiz için konsol kiriş ucuna monotonik olarak yer değiştirme uygulanmıştır. Analizlerde doğrusal olmayan malzeme ve geometri değişimi dikkate alınmıştır. Ayrıca, kolon, kiriş, bulon, levha gibi parçalar arasındaki temaslar, doğrusal veya doğrusal olmayan durum olarak dikkate alınmıştır. Birleşimler, kuvvet taşıma kapasitesi, moment -dönme eğrisi, panel bölgesindeki şekil değiştirmeler ve bulon çekme kuvvetleri bakımından birbirleriyle karşılaştırılmıştır. Yapılan incelemelere göre, panel bölgesinin güçlendirilmesi kolondaki panel bölgesinin şekil değiştirmesinin azalmasına fakat kiriş başlıklarının ve gövdesinin daha erken burkulmasına ve dönme kapasitelerinin azalmasına neden olmaktadır.Anahtar Kelimeler: Alın levhalı bulonlu birleşim, panel bölgesi güçlendirmesi, sonlu eleman analizi, doğrusal olmayan analiz THE EFFECT OF REINFORCING PANEL ZONE OF BOLTED END PLATE COLUMN BEAM CONNECTIONS ABSTRACTThe aim of this study is to assess the efficiency of changing thickness of end plate and reinforcing panel zone in bolted end plate column-beam connections that are performed by finite element analyses under monotonic loading. In the first phase of the study, finite element analyses of two bolted end plate connections which were taken from literature were performed and the experimental results from the literature and the numerical results of the present study were compared. In the second phase, effects of increasing the end plate thickness and the effects of reinforcing panel zone of connections, taken from the literature, were investigated. To reinforce the panel zone, diagonal braces or column web doubler plates were used. Pretensioned bolts were used in connections and monotonic displacement loading are applied to end of cantilever beam. Material and geometry nonlinearities were considered in the analyses. The linear or nonlinear contacts between connection parts such as column, beam, bolt and plate were considered. Connections were evaluated in terms of loading capacity, moment -rotation curve, plastic strain distributions of panel zone and bolt tension forces. The results reveal that reinforcing panel zone causes the plastic strains of column panel zone to decrease but resulting in earlier buckling of beam flange and beam web and reductions in the rotational capacity of the connection.
