Abstract

PurposeThis study presents a numerical modeling by the finite element method of galvanic corrosion between the bolt (cathode) and the end plate (anode). The bolt is made of three types of stainless steel: austenitic (SS304L, SS316L), martensitic (SS410, SS420) and duplex (32,101), and the end plate is made of carbon steel (S235JR).Design/methodology/approachFinite element modeling.FindingsThe results obtained show, on the one hand, that this corrosion rate increases as the conductivity increases, on the other hand, the stainless steels having the highest corrosion resistance causes a considerable loss of mass of the end plate and subsequently a decrease in the lifetime of the bolted joint.Originality/valueThe galvanic corrosion of beam to column bolted joint with end plate, used in steel structures, was studied in order to determine the corrosion rate of the end plate and subsequently to predict the total lifetime of the bolted joint.

结构螺栓连接中不同类型不锈钢和碳钢之间电偶腐蚀中导电性影响的有限元建模

目的本研究采用有限元方法对螺栓（阴极）和端板（阳极）之间的电偶腐蚀进行了数值模拟。螺栓由奥氏体（SS304L、SS316L）、马氏体（SS410、SS420）和双相（32101）三种类型的不锈钢制成，端板由碳钢（S235JR）制成。设计/方法/方法有限元建模。研究结果表明，一方面，这种腐蚀速率随着电导率的增加而增加，另一方面，具有最高耐腐蚀性的不锈钢会导致端板质量的显著损失，从而降低螺栓接头的寿命。独创性/价值研究了钢结构中使用的带端板的梁柱螺栓连接的电偶腐蚀，以确定端板的腐蚀速率，进而预测螺栓连接的总寿命。

期刊介绍： The International Journal of Building Pathology and Adaptation publishes findings on contemporary and original research towards sustaining, maintaining and managing existing buildings. The journal provides an interdisciplinary approach to the study of buildings, their performance and adaptation in order to develop appropriate technical and management solutions. This requires an holistic understanding of the complex interactions between the materials, components, occupants, design and environment, demanding the application and development of methodologies for diagnosis, prognosis and treatment in this multidisciplinary area. With rapid technological developments, a changing climate and more extreme weather, coupled with developing societal demands, the challenges to the professions responsible are complex and varied; solutions need to be rigorously researched and tested to navigate the dynamic context in which today''s buildings are to be sustained. Within this context, the scope and coverage of the journal incorporates the following indicative topics: • Behavioural and human responses • Building defects and prognosis • Building adaptation and retrofit • Building conservation and restoration • Building Information Modelling (BIM) • Building and planning regulations and legislation • Building technology • Conflict avoidance, management and disputes resolution • Digital information and communication technologies • Education and training • Environmental performance • Energy management • Health, safety and welfare issues • Healthy enclosures • Innovations and innovative technologies • Law and practice of dilapidation • Maintenance and refurbishment • Materials testing • Policy formulation and development • Project management • Resilience • Structural considerations • Surveying methodologies and techniques • Sustainability and climate change • Valuation and financial investment
