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.

On behalf of my co-authors, I would like to thank you for the opportunity to resubmit a revised copy of this manuscript entitled "Mechanical model for determining the critical load of plane frames with semi-rigid joints subjected to static". I would also like to take this opportunity to express our thanks to the reviewers for the positive feedback and helpful comments that have led to the improvements. Using feedback received from the reviewers, the article has undergone major revisions to its content. A new section has been added, entitled "Significance of the research", new material has also been added to the Introduction, and the references list revised accordingly. The contribution to knowledge of the article is now more firmly established and clearly spelled out. We believe have resulted in an improved revised manuscript, which you will find uploaded alongside this document. The manuscript has been revised to address the reviewer comments, which are appended alongside our responses to this letter. We have also included a separate document that highlights the differences between the work of Chen et al. that the reviewer referred to and the current study. This was not included in the article as it was not an aim in itself, however it is now referred to and briefly described in the revised manuscript.

This piece of work aims at the modeling and using the finite element method approach (FEM) to analyze the fatigue behavior of bolted beam to column end-plate connection in the structural steel framework subjected to static loading. A detailed three dimensional (3D) simulation model of the bolted beam to column end-plate connection is constructed in PRO-E wildfire and it is analyzed in the ANSYS workbench to obtain its behavior. The bolted end-plate connection is chosen as an important type of beam to column joint. The end-plate connection is chosen for its complexity in the analysis and behavior due to the number of connection components and their inheritable behavior. The solid elements, bonded contact and the bolt pretension are included to obtain the behavior of the structure. The FEA results of the structure with or without bolt pretension are compared with the available literature. At last the fatigue behavior of connections under over tensioning is presented in this work.
