Abstract

In the Northridge and Kobe earthquakes, brittle failure of the welded beam-to-column connections was observed in steel structures. So, bolted connections were considered as an alternative to these kinds of connections. Extended end-plate beam-to-column con-nection is one of the most commonly used connections in steel structure. In this article, the behavior of the sloped extended end-plate beam-to-column connections is studied. Finite element method was used to investigate the behavior of the connection by ABAQUS software. The main aim of the study was to investigate the cyclic behavior of the four beam-to-column connections with beam angles of 0, 10, 15, and 20 degrees with respect to horizon. Also, the behavior of the mentioned connections was compared with extended end-plate connections with perpendicular angle. Results showed that the ductility and moment-resisting capacity of the sloped extended end-plate beam-to-column connections decrease by increasing beam angle, but rotational and moment-resisting capacities of the models satisfy the limitation of the design codes such as 0.04 drift limit for bearing capacity before failure.

倾斜扩展端板梁柱连接循环性能评估

在北岭地震和神户地震中，观察到钢结构的焊接梁柱连接发生脆性破坏。因此，螺栓连接被认为是这些连接的替代方案。延伸端板梁柱连接是钢结构中最常用的连接方式之一。本文对倾斜扩展端板梁柱连接的性能进行了研究。采用ABAQUS软件对连接进行有限元分析。该研究的主要目的是研究四个梁对柱连接的循环行为，梁的角度分别为0度、10度、15度和20度。并与具有垂直角的扩展端板连接进行了性能比较。结果表明:随着梁角的增大，斜向扩展端板梁柱连接的延性和抗弯矩能力降低，但模型的转动和抗弯矩能力满足设计规范对破坏前承载力的0.04漂移限值等限制;

期刊介绍： Periodica Polytechnica Civil Engineering is a peer reviewed scientific journal published by the Faculty of Civil Engineering of the Budapest University of Technology and Economics. It was founded in 1957. Publication frequency: quarterly. Periodica Polytechnica Civil Engineering publishes both research and application oriented papers, in the area of civil engineering. The main scope of the journal is to publish original research articles in the wide field of civil engineering, including geodesy and surveying, construction materials and engineering geology, photogrammetry and geoinformatics, geotechnics, structural engineering, architectural engineering, structural mechanics, highway and railway engineering, hydraulic and water resources engineering, sanitary and environmental engineering, engineering optimisation and history of civil engineering. The journal is abstracted by several international databases, see the main page.
